Lattice Vibrations and Heat Capacityed..Let us consider a crystal lattice at low temperatures. We may expect each atom forming the lattice to execute small oscillations around the equilibrium position. For illustration let us consider the one-dimensional lattice shown in Figure 2.1.

Boltzmann Equation Methodthe conductivity is obtained..In the method of a Boltzmann equation the qualitative arguments in the simple kinetic theory will be formulated in more precise terms. In some simple cases, the description of the transport phenomena by this method is exact. In more complicated cases this method is an approximation, but it is widely used.

Cyclotron Resonancegnetic field is applied to a pure sample at liquid helium temperatures. The sign of the charge carrier can be determined by using the circularly polarized lasers. The data are analyzed in terms of Shockley’s formula or its simplified version. Most often the effective masses for a conductor are determined directly after simple analyses.

We diagonalize this tensor by introducing the principal masses and the principal axes of the inverse-mass tensor associated with the Fermi surface. Using these equations, we demonstrate that the “el
