Properties of ZnSe/Al2O3 Nanostructures Obtained by RF Magnetron Sputtering

Abstract

Experimental data for the synthesis of ZnSe/Al₂O₃ nanostructures utilizing a technology widely used in integrated circuit (IC) production are reported. It has been shown that the refractive index and size of the coherent scattering domains grow, whereas the energy bandgap decreases, with an increase in ZnSe width. It has been supposed that samples with a ZnSe width of 9 Å contain a ZnSeO₃ compound and/or ZnSe ⋅ Al₂O₃ complex compound. Multilayer heterostructures with a ZnSe width more than 9 Å contain cubic ZnSe nanocrystallites.
