1 Chapter 41 In this chapter we focus on a goal of physics that has become enormously important in the last half century. That goal is to answer the question: What are the mechanisms by which a material conducts, or does not conduct electricity? The answers are complex since they involve applying quantum mechanics not just to individual particles and atoms, but to a tremendous number of particles and atoms grouped together and interacting. Scientists and engineers have made great strides in the quantum physics of materials science, which is why we have computers, calculators, cell phones, and many other types of solid-state devices. We begin by characterizing solids that conduct electricity and those that do not. Conduction of Electricity in Solids 41-
