[edit] Summary

Schematic illustration of defects in a compound solid, using GaAs as an example. The defect notation is such that the upper-case letters stand for atoms or vacancies (V) on a lattice site, and the subscripts for the lattice site in a perfect crystal. The subscript i stands for an interstitial site and the subscript S for a substitutional site. Thus e.g. As_i stands for a As atom on an interstitial site, V_Ga for a missing atom on the Ga sublattice, Ga_As for a Ga antisite atom on the As sublattice, and B_S for a B atom on a substitutional site. This notation is a variety of Kroger-Vink Notation for non-ionic solids. Note that this 2D illustration does of course not correspond to the real zincblende 3D crystal structure of GaAs. Kai Nordlund, made originally with Framemaker in 2000 for lecture notes in a course on Solid State Physics in Swedish, translated to English in 2007 with gimp.
