摘要：The effect of compressive or tensile plane-stress on formation energies and electronic properties of point defects in Si single crystal was studied by first principles approach for in-plane strain up to 5.0 %. It was found that the formation energy of interstitial Si ( I ) decreased under tensile in-plane strain. On the other hand, the formation energy of vacancy ( V ) decreased under compressive in-plane strain. The most stable states of I and V in intrinsic Si were I ⁺² at T site and V ⁰ respectively, independent of type and value of the in-plane strain.
