Atomic Force Microscopy and Structural Studies of MBE-Grown CdF2 Layers on CaF2(111)
Abstract
The possibility of epitaxial CdF2 growth on CaF2 (1-bar,1,1) substrates in a wide growth temperature range of 100 - 500 C has been demonstrated, It is found that there are pyramidal mounds on CdF2 with a typical lateral size 30-60 nm at 100 C and 100-150 nm at 300 C. The angle between its facets and the growth plane is about 10 deg. At higher growth temperatures, the surface morphology drastically changes to large (1000-1500 nm) round islands formed by one-monolayer steps and 100 nm terraces. This indicates layer-by-layer growth. The RBS and XRD measurements show that the crystalline quality of the structures rapidly improves with the growth temperature.
