IntroductionTraditional solid-state physics is based on the concept of the perfect crystalline solid, sometimes with a relatively low density of defects. This perfect crystallinity has played a crucial role in the development of the subject, with Bloch's theorem providing the central conceptual base. Concepts that arise from this theorem, such as bands, Brillouin zones, vertical transitions, effective mass and heavy and light holes, are really only well-defined in a perfect infinite crystal. In the absence of crystallinity none of these concepts is strictly valid, though in some cases it provides a useful starting point. In general, however, a new approach is required to characterize electrons and phonons in disordered solids.When we consider low-dimensional structures Bloch's theorem may or may not be valid. There is nothing intrinsic to low dimensionality which invalidates it. Many of the simple examples in quantum mechanics and solid-state physics textbooks are, in fact, one-dimensional (e.g. the particle in a box, the Kronig–Penney model). Indeed, in a quantum well prepared by any of the standard growth methods (Chapter 1), much of the physics can be understood by using first-year undergraduate quantum mechanics and the effective mass approximation (Chapter 2). This is because a region of adjacent GaAs layers in AlxGa1−xAs can, for many purposes, be regarded as a perfect potential well. By doping the AlGaAs, the electrons in the well can be spatially separated from the scattering due to the ionized donor atoms (Chapter 3).

Charge depletion from 20 monolayers Of n+-In0.53Ga0.47As, uniformly doped with Si donors and embedded within Be-doped In0.53Ga0.47As, has been studied at 1.2 K by magnetotransport measurements. Electron subband energies and densities associated with the n+-In0.53Ga0.47As potential well prove sensitive to the presence of the acceptors at concentrations up to 3 × 1016 Cm-3. Agreement between the experimental data and the electronic subband structure calculated self-consistently by solving the one-dimensional Schrödinger and Poisson equations is excellent. The results suggest that intentional background acceptor doping could be a useful mechanism for tuning subband fillings and energies in potential wells formed by highly confined donors. © 1999 American Institute of Physics.
