초록

The energy gaps of undoped and Cr doped GaAs and $Al_{0-3}Ga_{0-7}As$ was measured nondestructively using surface acoustic wave (SAW) technique. The result is good agreement with other reported result. This technique is inexpensive and simple one for the measurement of mole fraction of $Al_xGa_{1-x}As$.
