SQS: Special Quasi-random Structures
Definition:A technique to simulate random disorder in finite sized supercell
Explanation:The SQS approach is used to investigate substitutional random alloys. In SQS, randomness is introduced by mimicking as closely as possible the correlation functions of an infinite random alloy within a finite supercell.
