โฆ Synopsis
In 1957, Landauer revolutionized the approach to the treatment of transport in condensed matter systems through the concept that the conductance could be directly related to the transmission coefficient through the system. Recently, this idea has become all pervasive in the study of mesoscopic systems, Here, we discuss the transport of ballistic carriers through strongly confined (but open) systems, known as quantum dots. The idea of transmission allows the connection of both classical and quantum concepts, and this opens the door to extend these studies to that of the quantum-to-classical transition.

Recent experiments have examined the magnetoconductance properties of mesoscopic quantum dots, defined in high mobility GaAs/AlGaAs heterojunctions utilizing split-gate techniques. Here, we report on a submicron, square quantum dot defined in a pseudomorphic InGaAs/GaAs single quantum well through a
We theoretically investigate the ballistic conductance of hollow quantum wires made of a two-dimensional electron gas occupying a cylindrical surface. The dependence of the conductance on the electron Fermi momentum differs drastically from the conventional case of a strip-like wire. We trace the ev
