Preferred term

Vacancy  

Definition

  • 1. In crystallography, a vacancy is a type of point defect in a crystal where an atom is missing from one of the lattice sites. (Wikipedia). 2. The term vacancy (or interstitial) defect may be understood to occur if in a volume element of the lattice, a particle is missing or contains an excess particle, with respect to the ideal lattice, independent of whether at that point or in its immediate vicinity particles deviate from their normal position. (ScienceDirect, Comprehensive Materials Processing, 2014)
