... Abstract In a perfect crystalline structure, there is an orderly repetition of the lattice in every direction in space. Real crystals contain a considerable number of imperfections, or defects, that affect their physical, chemical, mechanical, and electronic properties. Defects play...

Contributions from Transitions and Defects The specific heat for well-behaved (Debye-type) materials consists of contributions from lattice vibrations and from free electrons in the case of electrical conductors. The specific heats for these materials have a characteristic temperature relationship...

It begins with an overview of the atomic nature of matter and the forces that link atoms together in crystal lattice structures. It discusses the types of imperfections (or defects) that occur in the crystal...

Changes in impurity and defect content, which are minor from an industrial standpoint, may cause dramatic changes in the low-temperature resistivity. For example, recent measurements of commercial copper satisfying the CD...

... for diffusing atoms. However, such vacancies should form in a way that does not alter the charge of the oxide. Here, Schottky and Frenkel defects assist diffusion, as the cations diffuse through cationic vacancies and the anions diffuse through the anionic vacancies. The activation energies may differ for both...

... ( Collings, 1983 ). There are many modifications to the crystal lattice that must be accounted for in real solids: anisotropy, defects and impurities, the surface, polycrystallinity, transformations, and many others. Most theoretical developments treat these as minor perturbations on the general lattice...

During the irradiation of an alloy, some constituents of the alloy migrate toward point defect sinks, such as grain boundaries...
