Strain profile and size dependent electronic bandstructure of Type-I CdS/CdSe quantum ring

We study the strain profiles of Type-I CdS/CdSe quantum ring (QR) using the Valence force field method with Keating potential. The strain affects its electronic bandstructure which is calculated for varying QR widths using an effective mass envelope function theory based 8-band k·p model. This is followed by an electron-hole charge distribution study of the QR.
