http://www.ioffe.ru/SVA/NSM/Semicond/GaAs/ WebEquation. The energy band gap E g of Al x Ga 1-x As alloys depends on the aluminum content x. In the range of x < x c = 0.45 the gap is direct. At x > x c the gap is indirect. At room temperature (300 K) the dependency of the direct gap on aluminum content x can be calculated by the equation.
