For both Si and GaAs the maximum valence band energy of an electron occurs at Â¯p= 0. The minimum energy of the conduction band electron in GaAs also occurs for Â¯p= 0, hence a transition across the bandgap only requires an E g energy absorbtion or emission. Because of this, GaAs is called a direct semi-conductor.
