Many-Body Effects on Tunneling of Electrons in Magnetic-Field-induced Quasi-One-dimensional Electron Systems in Semiconductor Nanowhiskers

Abstract

The effects of electron–electron interaction on tunneling in a semiconductor nanowhisker are studied in a magnetic quantum limit. We consider the system with which bulk and edge states coexist. In bulk states, the temperature dependence of the transmission probability is qualitatively similar to that of a one-dimensional electron system. We investigate the contributions of edge states on transmission probability in bulk states. Those contributions can be neglected within our approximation which takes into account only the most divergent terms at low temperatures.
