In contrast, P-type semiconductors use a dopant element from group III on the periodic table (such as boron, indium, or gallium). These elements have only three electrons in their valence shell ...

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

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 ...
