1.1 Introduction

In this chapter, we will learn about the fundamental nature of solids and how their defining properties are associated with quantum mechanical concepts of electrons and their energy. The exposure to the most essential concepts of solid‐state physics will greatly help us in understanding the nature of electroceramics and the multiple physical phenomena they can exhibit that form the basis for a large number of novel device applications that impact electronic and sensor technology. We have purposely tried to avoid the intricacies of mathematical models in describing these concepts because the goal here is not to produce another book on solid‐state physics but rather to make use of the essential features of various theoretical models in understanding the transport properties of electrons, uniqueness of semiconductors, and the scientific basis behind the dielectric properties of materials.

1.2 Defining Properties of Solids

Solids can be broadly classified as conductors, semiconductors, and insulators of which dielectrics are a subset. Another important group of solids are classified as high temperature superconductors. Because of the unique physical mechanisms involved in the origin of superconductivity, these materials are of a special category and will be treated as an independent class of materials. We will devote a section on superconductivity later in this chapter. So far as the other three groups are concerned, we can differentiate between them on the basis of their defining properties. For example, a conductor is defined by its capacity to facilitate the transport of an electrical current associated with the inherent material property that we call resistance. Similarly a semiconductor is defined by its energy gap (also, called bandgap) and a dielectric by its dielectric property. We discuss in this chapter, the origin of these properties and how they add uniqueness to materials.

1.2.1 Electrical Conductance (G)

All materials tend to resist the flow of an electric current by virtue of its built‐in resistance. The magnitude of current, I, is by the resistance, R (or, conductance, G) when a voltage, V, is applied between the two ends of a solid sample. This relationship is given by the famous law of physics universally known as the Ohm's law that was conceived in 1825–1826 by Gerog Ohm of Germany. It states that the current (I) generated between the two fixed points of a conductor (such as a metal) is ...
