✦ Synopsis

Metal-insulator-like (MI) behavior in semi-metallic Bi-nanowires and single crystals indicate that semimetals exhibit a combination of unusual features of metal-insulating behavior which are accompanied by anomalously high magnetoresistance. These effects make semimetallic Bi a potential candidate for use in magneto-electronic devices. The present study examines the magneto-transport properties of Bi-line structures, focusing on magnetic field driven MI transitions. Conventional patterning and deposition processes are applied for the fabrication of a device that consists of five Bi-lines with line-widths of 2 lm.

A metal-insulator transition at zero magnetic ÿeld is observed in Ga [Al]As-heterostructures where a high density of self-assembled InAs-quantum dots is located in the region of the two-dimensional electron gas (2DEG). This transition occurs only in samples with high dot densities. In contrast to ot
