Semiconductor materials, as one of the important materials for the production of electronic chips and other objects, are widely used in the aviation industry, electronic equipment and other fields.
There are pure natural semiconductors in nature, such as silicon and germanium. However, due to natural factors, most of their molecular structures are incomplete, so they cannot fully exert their own value. Most of these natural semiconductors are presented in the form of polycrystals.
However, in our modern Chinese history, there is such a person. Her contribution not only made a breakthrough in the field of semiconductor technology in China, but also provided an important contribution to the atomic bomb. She is our semiconductor scientist, Lin Lanying.
Lin Lanying, originally from Putian, Fujian, was born on February 7, 1918 and died on March 4, 2003 at the age of 85.
Speaking of Lin Lanying's life deeds, it can be described as rugged and great, ordinary but not mediocre. Lin Lanying's family conditions are not bad, and her parents have a good business in Fujian, which also allows Lin Lanying to live a happier life than others since she was a child.
However, speaking of which, Lin Lanying was still quite regrettable when she was a child. Because Lin Lanying's father has a good deal, they have always hoped to have a son who will inherit his father's business in the future.
After all, in the society at that time, it was generally a patriarchal era. They always think that their daughters will cost money and that they will marry when they grow up. Under the stubbornness of the old ideas, it is more pleasing to parents to have a son than a daughter.
But after more than four years, the couple gave birth to four babies, all of which were daughters. This can be a headache for the husband and wife, after the birth of the four "sisters", the parents sent them to other people's homes.
In the fifth year, Lin Lanying was born. After seeing that their children were still daughters, the husband and wife were helpless. Since it was destined by heaven, it was left behind. In this way, Lin Lanying was lucky to stay at home and thrived under the protection of her parents.
During these years, Lin Lanying's parents devoted all the best in the family to cultivating their daughter Lin Lanying. But these trainings are not about literature, but about teaching her how to manage the family's business.
Because their husband and wife did not have a son, it is impossible for them to say that they will hand over their business to outsiders. And the only candidate is Lin Lanying
But Lin Lanying doesn't like these things, she prefers to learn knowledge than doing business. However, in the society at that time, people's thinking was relatively feudal. Everyone thinks that only sons can learn knowledge and culture, and daughters are best taught at home.
So, the husband and wife resolutely rejected Lin Lanying's request and gave her a serious ideological education. But these words were all taken as deaf ears by Lin Lanying. With her left ear in and out of her right ear, she didn't want to pay attention to her parents' arrangement.
I just want to be literate!I just want to read!After some quarrels, Lin Lanying also ran to find other elders in the family。She pleaded with them to grant her wish.
Of course, no matter which elder in the family was found, after hearing that Lin Lanying wanted to study, he had the same attitude as Lin Lanying's parents and rejected his request. They also feel that women should be at home with their husbands and children, rather than going out to study.
"What's the use of reading so many books?Aren't you going to get married and have children at home in the future?It's enough to learn basic survival skills!”
After seeing that the elders in the family disagreed, Lin Lanying was not discouraged. She immediately chose an extreme method to force her parents and elders to comply, that is, a hunger strike.
At first, her parents thought that Lin Lanying was just a tantrum, and she would come to eat when she was hungry. But when the first day passed and the second day passed, Lin Lanying never walked out of her room, which made her parents extremely worried.
On the third day, the parents finally couldn't sit still anymore and ran to the door of Lin Lanying's room together. However, Lin Lanying's attitude was the same as before.
If you don't let me go to school, I'll go on a hunger strike until I starve to death!This time, it completely scared the parents. After thinking for a while, the parents had no choice but to give up. After all, this can involve human lives, and it is impossible to starve your daughter to death, right?
In this way, Lin Lanying obtained the consent of the elders in the family through this extreme method. And parents also do what they say, since they promised their daughter, they must implement it. Otherwise, if Lin Lanying went on a hunger strike again, they wouldn't have the energy.
Soon, Lin Lanying went through the enrollment procedures, and when she was 6 years old, she entered the first school in her life. Lin Lanying, who is only 6 years old, is very sensible, she not only knows how to share housework for the family, but also learns to cook and can take care of her family alone.
And Lin Lanying would get up early every day before going to school, finish the housework at home, make a breakfast, and then happily run to school.
When she got home, she would take care of the housework without saying a word, and only run to do her homework when she had finished cleaning up.
Lin Lanying's diligence was seen by her parents and hurt in her heart. The daughter born to him turned out to be so sensible. At the age of 6, he had to take care of his family work and go to school by himself.
Parents are also very relieved about Lin Lanying, at least if Lin Lanying has no way out of studying, she will not starve herself to death in the future. However, her parents never expected that Lin Lanying would not only have good academic performance in such a state, but also be the best in school.
Lin Lanying showed her super high learning talent when she was in elementary school. Whether it is exams or homework, she is able to achieve the best possible score. This made her an extremely eye-catching presence in the crowd during her elementary school years.
After the principal discovered Lin Lanying's outstanding learning talent, he immediately contacted Lin Lanying's parents. I hope they can continue to agree to Lin Lanying to continue studying, and he will personally recommend Lin Lanying to enter Liqing Middle School and be exempted from the exam.
But her parents still didn't want Lin Lanying to continue studying. Although the principal personally proposed it, her parents preferred Lin Lanying to engage in her own business. So she told Lin Lanying that her family had no money for her to study.
But Lin Lanying heard the news that as long as she could get the first place in the school in the same grade in junior high school, she would be exempted from tuition. This made Delin Lanying extremely excited, and told her parents that as long as she could get the first place in the exam, she could be exempted from the tuition, hoping that her parents would agree.
Recalling the time when Lin Lanying was on a hunger strike, her parents could only reluctantly agree to Lin Lanying's request. And Lin Lanying proved herself with her actions, not only in the first year of junior high school, but also in the past three years, her results have always been the first in the whole grade.
In this regard, Lin Lanying was not proud and proud. In the days that followed, she was diligent in her studies. Finally, in 1936, she was admitted to the local Union University, where she majored in physics.
At the time, the school was able to provide a springboard for students to study in the United States. Lin Lanying wanted to miss this opportunity, she wanted to go out and open her eyes, and she hoped to learn new knowledge.
After negotiating with her parents, Lin Lanying also successfully went abroad for further study, and also obtained a doctorate from the University of Pennsylvania.
Lin Lanying also opened the way for the first female doctor at the University of Pennsylvania, and was also the first Chinese female doctor at the University of Pennsylvania.
After that, she was hired by Sophinia, which offered her a very attractive salary.
After years of study and precipitation, Lin Lanying has achieved good results. In one study, she and her team members successfully developed monocrystalline silicon and monocrystalline germanium. This is a milestone symbol in the field of semiconductor materials.
And during this time, a letter from ** made her heart extremely moved. We all know that in the early days of the founding of the People's Republic of China, China was still in the stage of development and exploration. There is a shortage of talent in many fields, which also leads to the stagnation of the country's development.
The motherland needs these Chinese students who have studied abroad to return to China and cooperate with domestic scientists and R&D personnel to build a better future for the motherland.
So, Lin Lanying didn't say a word, and after sorting out everything, she went to the company to resign. The reason is that the parents in the family are sick and need someone to take care of them.
Although it is easy to quit a job, it is difficult to return to China. How can Americans watch the people they have trained return to China with their research results?
Under the intervention of the high-level in the United States, Lin Lanying always couldn't buy a ticket, and no matter how she tried all kinds of methods, it was difficult to get a ticket.
At this time, she began to turn to her homeland for help. After learning about Lin Lanying's situation, ** got a ticket for her.
However, when it came time to board the ship, something happened again. After learning of Lin Lanying's importance, the US authorities immediately asked the staff to conduct a severe search on Lin Lanying.
However, after several searches, nothing was found, only a thick stack of dollars and two small glass bottles.
After seeing so many dollars, Lin Lanying also guessed the other party's thoughts, and even told them that these dollars were the income from working here.
However, the staff told them that the dollars could not be taken out of the country, so they confiscated the money. And the remaining two transparent glass bottles, no matter how the other party looks at them, they can't see the reason.
Lin Lanying told him that this was a life-saving medicine that she had brought home. Because his parents were sick, and China currently did not have such advanced pills, he thought about taking them home to treat his parents.
After checking the instructions issued by her superiors, Lin Lanying did say that her parents were sick, and then she didn't suspect it, and directly asked her to bring the two bottles of "pills" on the boat. As everyone knows, these two bottles of "pills" are the monocrystalline silicon and monocrystalline germanium that the US authorities are looking for.
However, the wood has already been completed, and Lin Lanying has already embarked on the road to return to China. On the ship back home, she felt for the first time how clear and sweet the smell of the sea was.
The good expectations in her heart are constantly approaching him. She also thought that if she achieved good results, she must return to her country. To contribute to the cause of the motherland, but she did it.
Lin Lanying's life can be described as conscientious, she not only did not relax in the slightest after returning to China, but devoted herself to work as soon as possible. He gave all his knowledge to the motherland unconditionally.
With the help of Lin Lanying, China has also made rapid progress in the field of semiconductor materials. And with the concerted efforts of many scientists and researchers, the first atomic bomb of our country was also successfully detonated. Lin Lanying even won the Medal of Honor with two bombs and one star.
In realizing the freedom of research and development of semiconductor materials, China's aviation industry has also made great progress. As a result, China's international status has been continuously improved. In particular, countries that looked down on China before have only been able to pay attention to China's achievements after seeing such achievements in China.
Our country owes the credit to the researchers who were not afraid to do so.
It is because of their existence that the motherland is strong. Because of their existence, the people of the country can enjoy the peace of today.
Let us remember the hard work of our ancestors and learn from their precious qualities. At the same time, we also firmly believe that our country will prosper in the future
