| Abstract: | Photoluminescence (PL) properties of the E0, E0+Δ0, and E+ bands in an x=0.62% GaAs1−xNx alloy were investigated in detail, including their peak position, linewidth, and line shape dependences on the excitation energy, excitation power, and temperature, using micro-PL. The hot electrons within the E+ band are found to exhibit highly unusual thermalization, which results in a large blueshift in its PL peak energy by >2kBT, suggesting peculiar density of states and carrier dynamics of the E+ band. |
