Abstract

We present the first known systematic mapping of quantum well and tunnel barrier thicknesses in a resonant tunneling structure by transport measurements. The technique derives a 1 Å averaged resolution for quantum well and barrier thicknesses, independently for the quantum well and adjacent tunnel barriers. Contour maps of the structure reveal an asymmetric shallow ring growth structure for one of the epilayers. Current-voltage characteristics and temperature dependence of the resonant tunneling structures will also be discussed.
