Abstract

The characteristics of a novel backgated two-dimensional electron gas (2DEG) system and its application to layers and nanostructures are summarized. In the backgated system, the 2DEG is formed in an undoped heterostructure through a field effect, and we can expect high-mobility and precise controllability. We have successfully fabricated backgated electron bilayer systems, quantum point contacts and lateral periodic structures with a short period. The results clearly show that a backgated system has much potential for application to layers and nanostructures.
