Abstract

We report the results of hot electron electroluminescence (EL) experiments carried out on p-i-n GaAs/AlGaAs single barrier tunneling structures. The EL spectra show peaks arising from recombination of both ballistic and intervalley-scattered electrons with neutral acceptors in the p-type collector region. From the relative intensities of these EL features we have obtained direct spectroscopic measurements of the Γ-L and Γ-X intervalley scattering times for high energy ballistic electrons in GaAs.
