Inelastic and resonant tunneling in GaAs/AlAs heterostructures
Abstract
We report the observation of inelastic and resonant tunneling in a study of electronic transport perpendicular to single or multiple AlAs layers sandwiched between GaAs layers. First derivatives and second derivatives of the low temperature current- voltage curves (I-V) for samples with single, 50 Å thick, AlAs layers revealed structure at both the AlAs and GaAs longitudinal optical phonon energies. These were attributed to the inelastic excitation of AlAs phonons and to a self-energy effect in the GaAs, respectively. The I-V curves for samples with two AlAs barriers of approximately the same width exhibited negative resistance regions due to resonant tunneling.
