Answer 3

semiconductors are materials that have properties of conduction between non conductor such as wood and rubber and conductor such as copper and iron and for example is silicon

Answer 4

Answer 5

A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current.

Answer 6

what is intrinsic samiconductor?

Answer 7

An intrinsic semiconductor material is chemically very pure and possesses poor conductivity.

Answer 8

can u explain me what is hole?

Answer 9

a hollow place in a solid body or surface.

Answer 10

i meant hole in semiconductor

Answer 11

valence band and all that

Answer 12

An intrinsic semiconductor material is chemically very pure and possesses poor conductivity. It has equal numbers of negative carriers (electrons) and positive carriers (holes). A silicon crystal is different from an insulator because at any temperature above absolute zero temperature, there is a finite probability that an electron in the lattice will be knocked loose from its position, leaving behind an electron deficiency called a "hole".
