There exist a huge number of exotic semiconductor materials, almost as many as there are material science projects using them. Still, modern manufacturing is dominated by two basic types of ...

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 ...

William Shockley improved on this design with his junction transistor, a three-layer sandwich of different types of semiconductor. The diagram illustrates the basic design of an NPN junction ...

A group of Korean researchers have recently succeeded in developing new p-type semiconductor materials and thin-film ...

In this article, we explain what semiconductors are; how they work, with an eye to N-type vs. P-type semiconductors; what semiconductors are made of and how they're built; and where they are found ...
