Question

on which factors does the electrical conductivity of a pure semiconductor depend on a given temperature ​

Answer 1

Answer:

Electrical conductivity of a pure semiconductor depends upon:

1. The width of the forbidden band
2. Intrinsic charge carrier concentration.

Answer 2

Electrical conductivity of semiconductors depend on two factor

(i) Forbidden energy gap

(ii) Either it is intrinsic or extrinsic

Explanation:

Electrical conductivity of semiconductor mainly depends on the forbidden energy gap if forbidden energy gap will be more then electrical conductivity of semiconductor will be less and if forbidden energy gap will be less then electrical conductivity will be more

One other reason is that if the semiconductor is intrinsic means there is no impurity then conductivity will be low and if there is any impurity in semiconductor then conductivity will be high
