Abstract
A small laterally confined area of the two-dimensional electron gas (2DEG) separated from two wide 2DEG regions by potential barriers is considered. Transparencies of the barriers can be controlled by the split gate voltages. The analysis shows that the dc current through the device can be quantized in units of ef, where f is frequency of the gate voltage modulation.Keywords
