What is Transistor and How Does IT Work

This paper will mainly introduce the exact meaning of transistors and their detailed history and working principle. Transistor is a kind of solid semiconductor device, which has many functions, such as detection, rectification, amplification, switching, voltage stabilization, signal modulation and so on. As a variable current switch, the transistor can control the output current according to the input voltage. Unlike conventional mechanical switches, such as relays and relays, transistors use telecommunication signals to control their switching on and off, and the switching speed can be very fast, reaching over 100 GHz in the laboratory. In 2016, Lawrence Berkeley National Laboratory broke through. Physical limit, which reduces the most complex transistor process from 14nm to 1nm, has made a breakthrough in computing technology.
