Which one of the following is a p-type of semiconductor? A)germanium doped with antimony B)germanium doped with boron C)tellurium D)YBa₂Cu₃O₇

Question

Quizplus · Accepted Answer

Germanium doped with boron is a p-type semiconductor. Boron has one less valence electron than germanium, so when it is introduced into a germanium crystal lattice, it creates a "hole", or a vacant spot where an electron should be. These holes behavelike positively charged particles, making the semiconductor p-type. Germanium doped with antimony would be an n-type semiconductor. Tellurium is an element but not a doped semiconductor. The fourth option is not relevant to the question as it is a chemical formula rather than a semiconductor material.
