Abstract

Calorimetric methods which allow estimation of the point defect concentration in solids are reviewed. Special attention is paid to the calculation of defect parameters based on the analysis of excessive heat capacity, and to correlations between the thermodynamic parameters of melting and the energetic parameters of point defect formation. The applicability of the thermodynamic approach to the study of intrinsic disorder in solids is demonstrated.

Zusammenfassung

Kalorimetrische Methoden zur Abschätzung der Konzentration von Punktdefekten in Festkörpern werden zusammengestellt. Aufmerksamkeit verdienen die Berechnung von Defektparametern aus einer Untersuchung der Exzeß-Wärmekapazität und Korrelationen zwischen thermodynamischen Parametern des Schmelzens und energetischen Parametern der Punktdefektbildung. Die Anwendbarkeit eines thermodynamischen Ansatzes zur Untersuchung der Eigenfehlordnung in Festkörpern wird demonstriert.

Резуме

Представлено обозре ние калориметрическ их методов определения концентрации точечных дефектов в т вердых телах. Особое в нимание обращено на вычислен ие параметров дефектов, исходя из ан ализа избыточной теп лоемкости и корреляций между тер модинамическими параметрами плавлен ия и энергетическими параметрами образования точечны х дефектов. Показана применимос ть термодинамическо го подхода к изучению собственно го беспорядка в твердых телах.
