摘要
We study the electron behaviour in sharply edged semiconductor narrow layers or quantum wires. If the layers are sufficiently narrow, the energy spectrum extends below the threshold energy of the first quantum conduction channel created by the transverse confinement. This leads to the existence of a (possibly measurable) edge-confined current. The critical layer width is estimated and the example of a rectangular edge is treated numerically. © 1990.
