Who invented the transistor. strong> In 1947, transistors were considered to be one of the most important discoveries of the 20th century and the vital part of electronic circuits. In the research labs of Bell organizations, the largest telephone company in the world, the team consisting of John Bardeen strong> and Walter Brattain strong> under William Shockley strong> is a brand new breakthrough in technology
Bardeen and Brattain were struggling to find an alternative to the thermionic covers used in the reception, reinforcement and reflection of radio and telephone signals. These lamps, which can be broken quickly and costly, had to pass a certain temperature to warm up. They also consumed quite a lot of electricity.
The team made the first transistor from a thin layer of germanium. Two days before Christmas 1947, this transistor was fitted to a radio circuit, and Brattain wrote the following lines in his book: “This circuit really works. Because the transistor was just like a lamp, it strengthened the sound signal. But it was much smaller in size and in need of less energy. Few people believed that a tiny device could replace those big lamps. But Shockley and his team have made great strides in four years. In 1952, the transistor was reduced to one tenth of its original size, and it became much stronger. In 1957, 30 million transistors were produced per year. Scientists have begun using pure silicate crystals that can withstand much greater heat intensities than the germanium layer.
Transistors were manufactured that could carry current up to a hundred millionths of a second. Thanks to them pocket-type calculators, digital clocks were made. The transistors in the receivers of the radio and television received the place of the lamps. If it were not for these little awesome devices, satellite communications, spacecraft and moon could not be conquered by humans.
