At absolute zero, Si acts as

By increasing the temperature, the specific resistance of a conductor and a semiconductor

The energy band gap is maximum in

A strip of copper and another of germanium are cooled from room temperature to $80K.$ The resistance of

The difference in the variation of resistance with temperature in a metal and a semiconductor arises essentially due to the difference in the

In the middle of the depletion layer of a reverse- biased $p$-$n$ junction, the

A piece of copper and another of germanium are cooled from room temperature to $77K,$ the resistance of

The manifestation of band structure in solids is due to

When $p$-$n$ junction diode is forward biased then

The electrical conductivity of a semiconductor increases when electromagnetic radiation of wavelength shorter than $2480$ $nm$ is incident on it. The band gap in $(eV)$ for the semiconductor is
