Mechanism of Current Modulation by Optic Phonon Emission in Heterojunction Tunneling Experiments

摘要

We explain recent observations by Hickmott et al. of sequential longitudinal optic phonon emission in tunneling currents of GaAs-Al/sub x/Ga/sub 1-x/As heterojunctions in terms of inhomogeneous tunneling and a magnetopolaronic mass correction. 16 refs., 13 figs. (ERA citation 11:001793)
