The conduction band of a solid is partially filled at 0 K.will it be a conductor, a semiconductor or an insulator?

Draw energy band diagram of conductors, semiconductors and insulators.

A 0K temperature, a p -type semiconductor

Give band gap Eg value for conductor, Insulator and semiconductor

The valence band at 0 K is-

Give two examples of each of conductor insulator and semiconductor.

Assertion : The electrons in the conduction band have higher energy than those in the valence band of a semiconductor Reason : The conduction band lies above the energy gap and valence band lies below the energy gap.

The valence band and conduction band of a solid overlap at low temperature, the solid may be

What is the range of energy gap ( E_g ) in insulators , semiconductors and conductors ?

What is the resistance of an intrinsic semiconductor at 0K?

The band gap between the valence and the conduction bands in zinc oxide (ZnO) is 3.0eV.Suppose an electron in the conduction band combines with a hole in the valence band and the excess energy is released in the form of electromagnetic radiation .Find the maximum wavelength that can be emitted in this process.
