Tunneling Through III–V Low-Barrier Heterostructures
This paper deals with tunnelling through very low and thick Al x Ga 1−x As barriers. E xperimental results are presented and compared with theory. Measurements in a transverse magnetic field are also described, and their relationship to the tunnelling time discussed. They provide further confirmation of direct, “ballistic” tunnelling through thick barriers.
