Essentially, a transistor, as one of the foundational elements of modern electronic devices, is made up of three layers of a semiconductor material, typically silicon, each layer possessing a ...

Often, proposals for optical switching emphasize high speed as their main advantage, and they may indeed operate faster than silicon transistors 1,14.Note, however, that current CMOS transistors ...

But with the addition of tiny amounts of other elements, which provide carriers for electric current, they can become good conductors. The first transistor, invented in 1947, was the point-contact ...

The boundary between these two kinds of semiconductors is known as a P-N junction, and it's a crucial part of a transistor. In the presence of this junction, current can start to flow from one ...
