List of top Physics Questions on Intrinsic Semiconductor asked in CBSE Class XII

Write two points of difference between intrinsic and extrinsic semiconductors.

Write any two points of difference between intrinsic and extrinsic semiconductors.

The hole concentration in an intrinsic semiconductor is \(5\times10^{8}\,\text{m}^{-3}\). When it is doped with certain impurity, the electron concentration becomes \(4\times10^{12}\,\text{m}^{-3}\). Find the new value of the hole concentration. Also identify the type of new semiconductor formed after doping.

How are charge carriers created in an intrinsic semiconductor? Explain.
