Step Structures and Epitaxy on Semiconductor Surfaces

摘要

At present, there is considerable effort directed towards the fabrication and utilization of nanoscale semiconductor objects. This is, in part, to investigate the behavior of electrons within structures of sufficiently small dimensions to produce quantum confinement. Such so-called quantum dots and quantum wires have dimensions of typically a few hundred Angstroms. In addition, quantum dots and wires have been proposed as a route to develop many new device applications.
