Question

Why is the conductivity of n-type semi-conductor greater than that of the p-type semi-conductor even when both of these have same level of doping?

Answer 1

Answer:

The conductivity of the semi conductor is greater than the p-type semi conductor

Answer:

since despite the same level, the conductivity of an n-type will be much greater than the p-type semiconductor. The charge carrier of the n-type semiconductor is an electron, so therefore it will move faster than the hole which is the charge carrier of a p-type semiconductor.

Explanation:

Hope this helped.

Answer 2

Answer:

(1) In a p-type semiconductor, holes are majority charge carriers.

(2) Holes behave as positive charges. When a p-type semiconductor is connected to a battery, holes are attracted towards the negative terminal of the battery.

(3) Holes are transported, when there is movement of electrons.

(4) The drift speed of these electrons in a p-type semiconductor is less than that in an n-type semiconductor. Also the mobility of the holes is less than that of the electrons.

(5) The electrical conductivity depends on the mobility of charge carriers. Hence, the conductivity of an n-type semiconductor is greater than that of a p-type semiconductor even when both of these have the same level of doping.
