摘要：

Optical absorption spectra of MBE grown GaAs-AlAs superlattices with various thickness of the potential-well layer were measured in the temperature range up to 500 K. The excitonic absorption peak is observed even at a temperature of 500 K or higher. The broadening parameter GAMMA for the exciton peak was determined by a curve fitting. This parameter determines the temperature limit below which double absorption peaks due to heavy and light hole exciton are observed.
