Abstract

We present an electroluminescence (EL) and transport study of the tunnelling mechanisms in GaAs/AlAs/GaAs single barrier p-i-n tunnelling structures. We show that both Γ-X and X-Γ tunnelling processes arise from either elastic transfer involving the longitudinal X_z barrier states, or momentum conserving phonon assisted transfer involving transverse X_xy states. The tunnelling process is shown to be very strongly sequential.
