1947 Finally, there is a research team in the laboratory. There are three people in the research group, namely shockley, Badin and bratton. A research team composed of three people developed a transistor. At that time, transistors were not as widely used as today's transistors, but they found that transistors were also very great inventions in the 20th century. It also laid a certain foundation for the future microelectronics revolution. After the transistor was discovered, people can skillfully use this small and low-power electronic component to replace some large, inconvenient and high-power electron tubes.
The invention of transistor made an important contribution to the later generation of integrated circuits. In the first decade of the 20th century, many different materials were used in communication technology. At that time, the most widely used material was semiconductor material. By the middle of the 20th century, many people had collected minerals, which were widely used as semiconductors. The invention of transistor mainly dates back to Lillianfeld, an engineer at that time, who obtained the patent about transistor at that time. However, due to the low level of scientific and technological development at that time, it was difficult to make this material, and transistors could not be made.
In this way, people at that time lost a good opportunity to study transistors, and it was not until later that people tried to make the signal current flow in one direction with minerals that they found better mineral crystal materials. It was not until World War II that their theoretical research on silicon materials reached a certain height in the laboratory, and only after reaching this height did they lay a certain foundation for the invention of transistors.
