First-principles study of near surface point defects stability in Si (100) and SiGe(100)

Surface effects on the Frenkel pair defects stability in the vicinity of the Si(001) surface

“…Even though the importance of surface/ interface strain is well recognized [22][23][24][25], there are a relatively limited number of studies dealing with their effects on the stability of interstitials [26][27][28][29]. It was demonstrated that under strain, the formation energies of bulk defects (Frenkel pairs (FP), self-interstitial atoms) decrease.…”
