Methods for the Production of Materials,tion of components in materials that are grown from the melt. The conditions for the avoidance of constitutional supercooling are discussed. Various techniques for the production of thermoelectric materials by sintering are described. A brief outline of methods for making thick and thin films is included.

Thermoelectric Properties of Metals and Semiconductors, effective mass and positive holes are introduced. The theory makes use of Fermi–Dirac statistics and the degenerate and non-degenerate approximations. A distinction is drawn between the properties of metals, insulators and semiconductors. The important effects that appear when both electrons and ho

Optimisation and Selection of Semiconductor Thermoelements,r is defined and it is shown how it can change with the Fermi energy. A materials parameter that depends on the carrier mobility, the effective mass and the lattice thermal conductivity is introduced. It is shown how the lattice conductivity can vary from one material to another and how it varies wi

Minimising the Thermal Conductivity, presented. It is shown that boundary scattering of phonons may be significant even when their free path length is small. The relative effects of phonon and electron scattering are discussed and the importance of the size of the unit cell is considered. The phonon-glass electron-crystal principle is
