Uniaxial Stress and Temperature Dependences of Photoluminescence in GaAs1-xPx

Abstract
The uniaxial stress and temperature dependences of the photoluminescence in GaAs1-x P x (x≃0.38) are studied and three kinds of photoluminescence are observed. One of them is attributed to the surface anomaly and the other two to annihilation of the bound excitons and donor-acceptor pair recombination. By combining the results of the uniaxial stress effect and the temperature change of the photoluminescence, the transition mechanisms for the luminescence are discussed.
