Let `(Delta)E`denote the energy gap between the valence band and the conduction band.The population of conduction electrons (and of the holes)is roughly proportional to `e^(-Delta E//2kT).`Find the ratio of the concentration of conduction electrons in diamond to that in silicon at room tempareture 300K.`(Delta E)`for silicon is 1.1 ev and for diamond is 6.0eV.How many conduction electrons are likely to be in one cubic meter of diamond ?
