Introduction. Crystal defects can no longer be thought of as a scientific curiosity, but must be considered an important aspect of solid-state science. This is largely because many of the more interesting properties of crystalline solids are disproportionately dominated by effects due to a tiny concentration of imperfections in an otherwise perfect lattice.

This book surveys the theory of defects in solids, concentrating on the electronic structure of point defects in insulators and semiconductors. The relations between different approaches are described, and the predictions of the theory compared critically with experiment.

The physical assumptions and approximations are : Paperback. Richard J. Tilley, DSc, PhD, is Emeritus Professor in the School of Engineering at the University of Cardiff, Wales, UK.

He has published extensively in the area of solid-state materials science, including papers, fifteen book chapters, five textbooks, and numerous book reviews. Point Defects: Point defects are where an atom is missing or is in an irregular place in the lattice structure. Point defects include self interstitial atoms, interstitial impurity atoms, substitutional atoms and vacancies.

A self interstitial atom is an extra atom that has crowded its way into an interstitial void in the crystal Size: KB. Point, line and area defects arise in solids. The number and type of defects depend on several factors (e.g.

the concentration of vacancied can be controled by temperature). The properties of the materials are affected by defects (e.g. defects control mechanical, electrical, optical properties).

Point defects are accounted for when the crystallization process occurs at a very fast rate. These defects mainly happen due to deviation in the arrangement of constituting particles. In a crystalline solid, when the ideal arrangement of solids is distorted around a point/ atom it is called a point defect.

Lidiará This paper reviews present knowledge of the structure, energies and mobilities of so-called point defects in crystalline solids, i.e.

of vacant sites in the crystal lattice and of atoms in interstices of the crystal lattice. Such defects in the regular lattice may be created by. thermodynamics of defects • Ionic solids – Schottky and Frenkel defects, ionic conductivity, fast ion conductors • Transition metal oxides – Non-stochiometry and redox processes, cation and anion vacancies, electronic properties of defective oxides • Metals – Dislocations, grain boundaries, stacking faults, properties of engineering File Size: 1MB.

• (2) line defects: The defects which arise due to irregularities or deviations from ideal arrangement in entire row of of lattice point are called line defects.

• These irregularities are called crystal defects or crystal imperfections. POINT DEFECTS IN SOLIDS •(1) Vacancy defect. •(2) interstitial defect. POINT DEFECTS Point defects can be classified as self-interstitial or vacancy.

Vacancy Vacancy is the absenteeism of an atom at an atoms site. All solids contain vacancies, it is impossible to create solid materials without.

Self-interstitial We have self-interstitial when an atom in crowded into interstitial sites or small voids that is not. [] [] [] In this section we discuss the statistical physics of point defects in solids.

The principle goal is to relate macroscopic quantities (equilibrium concentrations and diffusion. Point defect: When the deviation or irregularities exists from ideal arrangement around a point or an atom in a crystalline substance the defect is called the point defect.

Line defect: When the deviation from the ideal arrangement exists in the entire row of lattice points the defect is called as line defect.

Types of the point defects: 1.Crystal defects can no longer be thought of as a scientific curiosity, but must be considered an important aspect of solid-state science.

This is largely because many of the more interesting properties of crystalline solids are disproportionately dominated by effects due to a tiny concentration of imperfections in an otherwise perfect lattice.
