Still, modern manufacturing is dominated by two basic types of semiconductors: N-type and P-type. Like carbon, silicon has four electrons in its outermost electron shell, so it can form four bonds.

The diagram illustrates the basic design of an NPN junction transistor. Two slices of N-type semiconductor, the emitter and the collector, form a sandwich with a layer of P-type semiconductor ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

What is the principle of CMOS technology? The principle of CMOS technology is to use a combination of n-type and p-type metal-oxide-semiconductor field effect transistors (MOSFETs) to implement logic ...

Firstly, the researchers processed 2D semiconductors using well-established ... approach to p-type 2D transistors (as opposed to the n-type devices used in this study), because their performance ...
