Which оf the fоllоwing аre correct? Pleаse specify аll that apply. In a semiconductor, there are electrons in the conduction band even at absolute zero. The conductivity of a semiconductor can be increased by using photons to excite electrons from the valence band into the conduction band. To do this, the photon energy must be at least as great as the band gap; lower energy photons will not be absorbed. A semiconductor has the same band structure as an insulator, but a smaller gap between the valence and conduction bands. As the temperature of a semiconductor increases, the population in the conduction band increases very rapidly, as does the electrical conductivity. A semiconductor at absolute zero has an empty conduction band above the full valence band.
