Indium antimonide has a band gap of 0.23eV between the valence and the conduction band.Find the temperature at which kT equal the band gap.

Assertion : The energy gap between the valence band and conduction band is greater in silicon than in germanium. Reason : Thermal energy produces fewer minority carriers in silicon than in germanium.
