|Title:||Structure, stability, and electronic properties of pseudomorphic (si)n/(ge)m superlattices||Authors:||Theodorou, George Os

|Keywords:||Thermodynamics;Electronics||Issue Date:||1993||Publisher:||APS American Physical Society||Source:||Physical Review B,1993, Volume 48, Issue 19, Pages 14238-14241||Abstract:||We investigate the structure, energetics, and electronic properties of (Si)5/(Ge)5 and (Si)3/(Ge)4 superlattices. Our analysis, based on the empirical-potential approach, shows that the thermodynamic stability of these superlattices decreases with increasing substrate lattice constant. Electronic properties are inferred from tight-binding calculations. Use of the interatomic distances obtained here and of those given by elastic theory leads to similar results for the band structure and transition probabilities.||URI:||http://ktisis.cut.ac.cy/handle/10488/7714||ISSN:||0163-1829||DOI:||10.1103/PhysRevB.48.14238||Rights:||© 1993 The American Physical Society.||Type:||Article|
