Publisher Summary Quantum transport is conveniently studied in a two-dimensional
electron gas (2DEG) because of the combination of a large Fermi wavelength and large …

The focused ion beam (FIB) is a powerful tool for fabrication, modification, and
characterization of materials down to the nanoscale. Starting with the gallium FIB, which was …

By tailoring the boundary of a narrow semiconductor channel to break its symmetry, we have
realized a type of nanometer-scale nonlinear device, which we refer to as self-switching …

Many magnetotransport experiments in two-dimensional electron systems have been
explained in recent years within the so-called edge-state model. Starting from a historical …

During six months from April to September 1994, the author visited 42 laboratories in eight
different European countries involved with research in nanostructures. The scientific thrusts …

The surface of shallow Ga [Al] As heterostructures is locally oxidized with an atomic force
microscope. The electron gas underneath the oxide is depleted. We demonstrate …

This article discusses applications of focused ion beam micro-and nanofabrication.
Emphasis is placed on illustrating the versatility of focused ion beam and dual-platform …

Graphene nanoribbons show unique properties and have attracted a lot of attention in the
recent past. Intensive theoretical and experimental studies on such nanostructures at both …

Grinding, thinning, beveling, and polishing are the first steps to shaping and structuring a
material. At first sight, these methods appear to be simple. However, some materials would …
