Structure and optical properties of ZnSe/SiO2 layered nanocomposites

Аннотация

Structure and optical properties of ZnSe/SiO₂ layered nanocomposites obtained using microwave magnetron sputtering have been studied. The nanocomposites are X-ray amorphous at relatively small thicknesses of the zinc selenide layers. When the thickness of the zinc selenide layers exceeds 20 Å, ZnSe/SiO₂ films contain SiO₂ amorphous phase and zinc selenide cubic nanocrystallites. It has been demonstrated that the thickness of zinc selenide layers affects the microstresses, refractive index, and band gap.
