Pressure Dependence of Time-Pesolved Photoluminescence in Ordered Ga_<0.5>In_<0.5>P
We have measured the time-resolved photoluminescence (TRPL) spectra of ordered Ga<SUB>0. 5</SUB>In<SUB>0. 5</SUB>P alloys at 12 K and for pressures up to ∼4 GPa. At lower pressures below ∼2 GPa, the PL spectra are found to consist of three emission bands whose decay profiles are quite different from each other. Above 3 GPa the PL spectra shows fast decays, which do not depend on the detection energy. We propose a model of type-II band alignment to explain the PL behavior observe at high pressures.
