WitrynaFrenkel defect is shown by an ionic substance in which there is a large difference in the size of ions, for example, ZnS, AgCl, AgBr, and AgI due to the small size of Zn 2 + and Ag + ions. Impurity Defect : If molten NaCl containing a little amount of SrCl 2 is crystallized, some of the sites of Na+ ions are occupied by Sr 2 + . When an impure liquid is cooled to its melting point the liquid, undergoing a phase transition, crystallizes around the impurities and becomes a crystalline solid. If there are no impurities then the liquid is said to be pure and can be supercooled below its melting point without becoming a solid. This occurs because the liquid has nothing to condense around so the solid cannot form a natural crystalline solid. The solid is eventually formed when dynamic arrest or glass transition occ…

WitrynaThis review describes several of the main techniques used to determine matrix element distributions and those which can provide a survey of impurity levels and assess deliberate doping concentrations in Cd x Hg 1 − x Te and CdTe-based substrate materials.
