What are the semiconductors in the periodic table?

Answer 1

Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to make impure.

Answer 2

There are two types of extrinsic semiconductors. They are a) n-type semiconductors

b) p-type semiconductors.

n-type semiconductors: These are impure by fifth group elements like phosphorous, arsenic, antimony. In this type of semiconductors majority charge carriers are electrons and minority charge carriers are holes. These are donors of electrons.

p-type semiconductors: These are impure by third group elements like boron,indium. In this

type of semiconductors majority charge carriers are holes and minority charge carriers are electrons. These are acceptors of electrons.

Answer 3

Semiconductors were originally made using specially doped germanium or silicon. Nowadays various specialized doped alloys are used.

Answer 4

A diode is the simplest possible semiconductor device, and most semiconductor chips and transistors are created with silicon.

Answer 5

The two main types of semiconductors are n-type and p-type.

Answer 6

You shouldn't write "the following" if you don't provide the list. Anyway, silicon and germanium are most commonly used as semiconductors.

Answer 7

The ones adjacent to silicon.

Answer 8

Semimetals
