Popis: Imperfect crystals behave statistically like liquid solutions, the crystal being the solvent and the imperfections the solutes. Application of the law of mass action to atomic and electronic reactions taking place in the crystal and between the crystal and the other phases leads to the notion that the concentrations of the various imperfections are interdependent as a result of reactions having partners in common. The consequences of this interdependence are demonstrated by means of a graphical method. Imperfections having opposite effective charges tend to increase each other's concentrations. Foreign atoms are incorporated in a manner dependent both on the energy levels caused by them and on the type of imperfection prevailing in the crystal in the absence of these foreign atoms. In monatomic solids the mechanism of incorporation can be influenced only through the temperature; in compounds it can also be influenced through the partial pressures of the components of the basis crystal. It is shown that these arguments given are valid irrespective of the type of bonding.
