Bonding in semiconductors

Besides semiconductor elements (e.g., silicon, carbon), there have been considerable efforts in the last several years devoted to the tight-binding modeling of metals. Since the strong directional d-band bonding in many body-centered cubic transition metals resembles the covalent bonding in semiconductors to some extent, they may provide good opportunities for TBMD approaches.

The present four volumes, published under the collective title of "Chemical Bonds in Solids," are the translation of the two Russian books "Chemical Bonds in Crystals" and "Chemical Bonds in Semiconductors." These contain the papers presented at the Conference on Chemical Bonds held in Minsk between May 28 and June 3, 1967, together with a few other papers (denoted by an asterisk) which have been specially incorporated. Earlier collections (also published by the Nauka i Tekhnika Press of the Belorussian Academy of Sciences) were entitled "Chemical Bonds in Semiconductors and Solids" (1965) and "Chemical Bonds in Semiconductors and Thermodynamics" (1966) and are available in English editions from Consultants Bureau, New York published in 1967 and 1968, respectively). 

The Minsk conferences on chemical bonds in semiconductor and other crystals have demonstrated clearly the importance of experimental determinations of the distribution of the electron density in crystals, the distribution of the potential in the crystal lattice, and the application of various methods to the calculation of the effective charges of ions and of accurate values of the atomic spacings and bond energies. It has been found possible to estimate various physical properties of crystals from the experimentally and theoretically determined atomic scattering functions and the electron density distributions in crystals. These problems are considered in several papers in the present collection. 

Some workers regard the atomic bonds in semiconductors as a special type which is independent of the other four types. It seems clear, however, that the chemical bonds in semiconductors do not represent an independent type of bonding but form the most general class, which extends from the center of the aforementioned tetrahedron to its vertices.
