Book 1972ted the interest of a wide circle of physicists, chemists, and engineers. Until recently, the most successful description of the properties of solids (including semi conductors) has been provided by the band theory, which still dominates the physics of solids. Nevertheless, it is clear that the mosPeristalsis 发表于 2025-3-30 16:32:28

Characteristic Features of the Physicochemical Structure of Chromium Disilicidemental and calculated density of CrSi., it is proposed that the high (10. cm.) hole density in stoichiometric samples at room temperature is due to the “molecular” imperfection of the crystal lattice.aggrieve 发表于 2025-3-31 03:57:28

Physicochemical Nature of Monosilicides with an FeSi-Type Structure cell and the . space group. Each atom in the cell is surrounded by seven atoms of the other kind: one very close, three further away, and three at an even greater distance. Each metal atom is associated with six relatively remote similar atoms. The most important crystallographic properties of compmembrane 发表于 2025-3-31 12:06:27
Chemical Bonds and Properties of the Higher Silicide of Manganesee materials are important in a number of metallurgical processes and also because of a number of recently discovered special applications for materials of this type. In addition to this, such studies are of a definite theoretical interest. It is known that there are, among the silicides, compounds wCT-angiography 发表于 2025-3-31 13:59:23
