Abstract

In the previous chapter we discussed systems in which the electron mean free path was short compared with typical device dimensions. The physics of transport becomes quite different in the opposite limit, i.e. when the system dimensions are small compared with the mean free path, requiring both high-mobility electrons and small systems. The high mobility of electrons can be achieved, for example, by modulation-doped structures at low temperatures, as discussed in Chap. 1. The typical scales of such structures are on the order of 1μm or below. Such small systems, which are macroscopic compared with one lattice constant, but still microscopic in actual size, are referred to as mesoscopic systems.
