The gain characteristics of heavily doped AlxGa1-xN/AlN: Si structures with x = 0.65 and 0.74 under optical pumping by a pulsed Nd:YAG laser radiation with lambda= 266 nm have been experimentally studied at room temperature. The absolute values of the optical gains are (0.5–6)*10^3 сm-1 in the maximum of the luminescence spectrum at the excitation power density (8–600) kW/cm2. The obtained cross sections for the radiative and donor–acceptor recombination coincide with each other and exceed the 10^(-16) сm2.

Time-resolved luminescence and stimulated emission intensities has been experimentally investigated in heavily doped Al0.65Ga0.35N and Al0.74Ga0.26N structures under pulsed optical excitation. These results showed that the time decay of the luminescence and stimulated emission intensities for various wavelengths of the emitted spectrum and optical pumping intensities consisting of at least the fast and the slow components. Fast components with exponential time decay are responsible for the radiative recombination of nonequilibrium electrons on deep acceptors, while slow ones are responsible for the recombination of donor-acceptor pairs

Molecular-beam epitaxy (MBE) is potentially an extremely valuable tool for growing III-V compounds. The value of the technique results partly from the ease with which controlled layers of precisely determined composition can be grown, and partly from the ability that it provides for growing accurately doped layers.
