Which best describes a p-type semiconductor? a) They have holes that are positively charged. b) They have weakly bound electrons that can flow easily. c) They emit electrons at one end of a vacuum tube. d) They emit electron beams that strike phosphors.

They have holes that are positively charged

Explanation:

There are two types of semiconductors i.e. p-type and n-type.

p-type is a type of semiconductor that is formed when a trivalent impurity is added to an intrinsic semiconductor like silicon or germanium. Boron (B), Gallium (Ga), Indium(In), Aluminium(Al) etc are trivalent impurities. Due to this combination, a large number of holes are created in it.

Hence, p-types of semiconductors have holes that are positively charged.

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.
