Abstract

Microfabrication through the use of electron-beam lithography has allowed the creation of nanostructures with interesting and novel properties, and it is now possible to create potential-induced lateral surface superlattices. The magnetoconductance in such structures can be expected to be significantly different from that of normal quasi-two-dimensional systems. Here, we discuss the theoretical understanding and experimental studies that show the presence of the Aharonov-Bohm effect, universal conductance fluctuations, and structure in VH and σxx with h/e and 2h/e periodicity in the flux coupled through each quantum well of the superlattice. At high VSD, we have seen evidence for negative differential conductivity, which might be attributable to Bloch oscillations.
