Abstract
The allowed and forbidden transitions in MBE grown on (001) GaAs subst rates (AlGa)As/GaAs multiple quantum well structures were investigated by photoreflectance spectroscopy (PR). The optical transition energy values obtained from experiment were compared with ones calculated by using the envelope function approximation. Good agreement between both results was found. The temperature dependence, down to the liquid nit rogen temperature, of the 1 IH transition was analysed. (C) 1998 Elsev ier Science Ltd. All rights reserved.
