内容記述 |
Photoluminescence (PL) of an unintentionally doped Al0.5Ga0.5As/GaAs multiple quantum well (MQW) has been measured at temperatures from 5 to 400 K. It was found that the ratio of the intensity of the n = 1 electron-light hole transition (1e-1lh) to that of the n = 1 electron-heavy hole transition (1e-1hh) can be described by an exponential function of reciprocal temperature. The excitation-power dependence of the 1e-1hh transition PL intensity measured at temperatures from 5 to 296 K in steps of 15–20 K showed that the relative contribution of free-carrier recombination gradually increases from 5 to 120 K and then remains constant. This tendency was confirmed by the temperature dependence of the energy difference between the 1e-1hh transition and the bulk GaAs band gap. |
