Much of our understanding of electron transport in solids is based on the semiclassical picture that views electrons as particles obeying Newtonian mechanics in an external field and occasionally scattered by phonons and impurities. Quantum effects such as size quantization and tunneling, however, cannot be understood within this conceptual framework.
