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 ...

P- and N-type semiconductors are made with different ... Most early commercial transistors were junction transistors and are the type used in the activity on the next two pages.

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

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 ...

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 ...
