In a semiconductor, the conductivity increases with the increase in temperature due to

As the temperature of the semiconductor is increased, the mobility of electrons and holes

The intrinsic carrier concentration of silicon sample at $300 \mathrm{K}$ is $1.5\times {10}^{16}/{\mathrm{m}}^3.$ What is the density of minority carrier? (after doping, the number of majority carriers is $\left.5\times {10}^{20}/{\mathrm{m}}^3\right)$

In a semiconductor, the concentration of minority carriers depends mainly on

An extrinsic semiconductor with electrons as majority carriers can be obtained by doping Ge or Si with

In a three phase full-wave rectifier of $100 \mathrm{Hz}$, the ripple frequency is

A zener breakdown occurs in a zener diode when

Silicon dioxide layer is found in which of the following devices?
