vacancy Physics a defect in a crystalline solid caused by the absence of an atom, ion, or molecule from its position in the crystal lattice Vacancy (also Schottky defect), a crystal defect owing to the absence of an atom or ion at a crystal-lattice point. Vacancies exist in all crystals, however carefully the crystals are grown. In a real crystal, vacancies arise and vanish as a result of the atoms’ thermal motion. The mechanism of vacancy formation can be represented as the discharge of atoms of the surface layer onto the surface with the subsequent transfer of the surface “holes” developed. Here, in place of bonds with three neighboring atoms, only one bond remains and the other two are broken. Consequently, the work necessary to form a vacancy is equal to the energy of two bonds. Vacancies migrate randomly in the crystal, changing places with neighboring atoms. The motion of a vacancy is the main cause of the intermixing (self-diffusion) of atoms in a crystal, as well as of the mutual diffusion of contacting crystals. A specific equilibrium concentration of vacancies corresponds to each temperature. The number of vacancies in metal crystals near the melting point reaches 1-2 percent of the number of atoms. For aluminum at room temperature, one vacancy occurs per 1012 atoms, and in metals such as silver and copper, the number of vacancies at room temperature is even smaller. However, despite the small concentration, vacancies substantially influence the physical properties of the crystal: for example, the density decreases and ionic conductance is produced. Vacancies play an important role in heat treatment processes, relaxation of metals, re-crystallization of metals, sintering, and other processes. REFERENCESWert, C, and R. Thomson.

vacancy[′vā·kən·sē] (solid-state physics) A defect in the form of an unoccupied lattice position in a crystal. Vacancy
VACANCY. A place which is empty. The term is principally applied to cases where an office is not filled.
2. By the constitution of the United States, the president has the power to fill up vacancies that may happen during the recess of the senate. Whether the president can create an office and fill it during the recess of the senate, seems to have been much questioned. Story, Const. Sec. 1553. See Serg. Const. Law, ch. 31; 1 Breese, R. 70. vacancy
VacancyA job that has not been filled. A job vacancy may occur when an employee quits or is terminated or when a company creates a new position. A large number of job vacancies in an area may indicate that unemployment is about to decline or that workers have sufficient job security to hold out for higher wages or other benefits. Alternatively, vacancies may indicate that the workforce is poorly trained for what needs to be done. See also: Help-Wanted Index.vacancy a JOB position offered by an employer that currently remains unfilled. Employers may seek to fill a vacant job position by REDEPLOYMENT of existing staff within their own firms or other organizations or may seek to take on new staff by advertising job positions in local and national newspapers, by using a private RECRUITMENT AGENCY or by accessing the government's network of JOB CENTRES.vacancy
