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 ...

Two slices of N-type semiconductor, the emitter and the collector, form a sandwich with a layer of P-type semiconductor, called the base. P- and N-type semiconductors are made with different ...

Bardeen, Brattain and Shockley had tested various combinations of p-type and n-type semiconductors under different conditions until they finally found a configuration that would allow a thin layer of ...

The use of n-type and p-type silicon is a foundation concept in the design of transistors. Pure silicon is not conductive. However, it can be made conductive by adding other elements to its ...
