Question

At ordinary temp the electrical conductivity
of semi Conductors in mho/meter is in the
range of​

Answer 1

A semiconductor has two types of charge carriers i.e. holes and electrons. The conductivity of a semiconductor is sum of conductivities of holes and electrons i.e. σ=eni(μh+μe). Therefore, electrical conduction in a semiconductor is due to holes and electrons both.

Answer 2

Answer:

Metals are conductors having conductivities in range of 107 (Ω-m)-1, while semiconductors have conductivities in range from 10-6 to 104 (Ω-m)-1, and materials with conductivity lower than 10-10(Ω-m)-1 are termed as insulators.
