摘要

We calculated for the first time the interband radiative recombination rate R in the wide-gap semiconductors GaN, InN and AlN crystallizing in the hexagonal wurtzite structure, and in ternary In_xGa_yAl_(1-x-y)N alloys including also binary solid solutions Ga_xAl_(1-x)N, In_xAl_(1-x)N and Ga_xIn_(1-x)N. All our calculations were based on experimental data on energy band structures and optical absorption spectra of the nitride materials. The radiative recombination coefficient B defined according to the equation R = Bnp, n and p being the carrier densities, is higher in InN and lower in GaN, taking intermediate values in AlN. For example, B=(2.7, 0.4 and 0.15) × 10~(-10)cm~3/s for InN, AlN and GaN, correspondingly. The carrier lifetime in GaN equals 60ns at 300K and n=1 × 10~(17)cm~(-3). The radiative recombination coefficient increases with the concentration of indium nitride in the ternary alloys.
