Abstract:
Gain characteristics of heavily doped Al$_{x}$Ga$_{1-x}$N : Si structures with c $x$ = 0.65 and 0.74 have been studied under pulsed optical pumping by Nd:YAG laser radiation at wavelength $\lambda$ = 266 nm. The absolute values of the optical gain measured at spectral maximum of the room-temperature luminescence spectrum reach (0.5 – 6) $\times$ 10$^3$ сm$^{-1}$ at an pumping power density of 8–600 kW/cm$^2$. Cross sections of the radiative and donor–acceptor recombination are close to each other and exceed 10$^{16}$ cm$^2$.
Keywords:
heavily doped structures, Al$_{x}$Ga$_{1-x}$N/AlN, gain characteristics.
