| Abstract: | The injected carrier induced absorption spectrum of linearly polarized light and photolumineacence spectrum in undoped CaAs film grown by MOVPE are determined experimentally. It show that the energy-gap and maximum of photolumineacence intensity are remakely decreased due to carrier injection. The carrier-induced changes in energy-gap and maximum of photolumineacence intensity are nonlinearly variations with the injected carrier concentrations. |
