Conduction of Electricity in Solids

REVIEW & SUMMARY Conduction Of Electrictiy In Solid

REVIEW & SUMMARY  Conduction Of Electricity In  Solid The Confinement Principle The confinement principle applies to waves of all kinds. including waves on a string and the mailer waves of quantum physics. It states that confinement leads t o quantization-that is. to the existence of discrete states with discrete energies. An Electron in an Infinite Potential Well An …

Metals

Metals The feature that defines a metal is that, as  shows, ~ highest occupied energy level falls Somewhere nellie “middle of an .energy band. If we’ apply a potential difference across a-metal, a current can exist because there are plenty of vacant levels at nearby higher energies into which electrons (the charge carriers in a metal) can jump. Thus, …

The Electrical Properties of Solids

The Electrical Properties of Solids We shall examine only crystalline solids-that is, solids whose atoms are arranged in a repetitive three-dimensional structure called a lattice. We shall not consider such solids as wood, plastic, glass, and rubber, whose atoms are not arranged in such repetitive patterns. Figure 42-1 shows the basic repetitive units (the unit cells) of the lattice …

SOLIDS

SOLIDS You have seen how well quantum physics works when we apply it to questions .involving individual atoms. In this chapter we hope to show, with a single broad example, that this theory works just as well when we apply it to questions involving assemblies of atoms in the form of solids. Every solid has an enormous range of …
