LABORATORY MANUAL FOR ENERGY BAND GAP EXPERIMENT
www.nitj.ac.inTheory: A semi-conductor (either doped or intrinsic) always possesses an energy gap between its valence and conduction bands (fig.1). For the conduction of electricity, a certain amount of energy is to be given to the electron so that it can jump from the valence band to the conduction band. The energy so needed is the measure of the energy gap ...

ee.stanford.eduThe simplest "k.p" band theory says that the electron effective mass, me, and the light hole effective mass, mlh, are approximately equal and proportional to the band gap energy. For GaAs, which has a band gap energy of ~ 1.5 eV, the actual values are me ~ 0.069 mo and mlh ~ 0.09 mo, where mo is the free electron mass.
