What is a semiconductor? Describe the two main types of semiconductor and contrast their conduction mechanism.

Text Solution

Verified by Experts

The Substance whose conductance lies between that of conductors (metals) and insulators are called semiconducutors . They have conductivity values ranging from `10^(-6) ` to `10^(4) Omega^(-1) m^(-1)`. Two main types of semi-conductors are n-type and p-type.
