Explain conductivity in semiconductors.

Semiconductors are semi-good electrical conductors because although their valence band is completely filled, the energy gap between the valance band and the conduction band is not too large. Hence some electrons can bridge it to become charge carriers. The difference between semiconductors and an insulator is the magnitude of the energy gap. For semiconductors Eg < 2eV and for Insulators Eg > 2eV.It is well known to us that the conductivity of a semiconductor depends on the concentration of free electrons in it

FAQ

What is Conductivity in semiconductors?
Conductivity in semiconductors, the conduction band electron, and valance band hole participate in electrical conduction and is represented as σ=n*[Charge-e]*µp+n0*[Charge-e]*µn or conductivity=Concentration of electrons in the conduction band*[Charge-e]*Mobility of holes+Majority carrier electron concentration*[Charge-e]*Mobility of electron. The concentration of electrons in the conduction band is the no. of electrons in the conduction band of the semiconductor, Mobility of holes is the ability of an hole to move through a metal or semiconductor, in the presence of applied electric field, Majority carrier electron concentration is the number of carriers in the conduction band with no externally applied bias. and Mobility of electron is defined as the magnitude of average drift velocity per unit electric field.
How to calculate Conductivity in semiconductors?
