Abstract
Polycrystalline CaS thin films were grown on Al2O3 films deposited on Si-wa fer using the atomic layer deposition (ALD) technique. The surface structur e of these films was studied by AFM and compared with respective SEM images . The polycrystalline film surfaces comprise regular shaped crystallites. F irst report of a possible growth mechanism is presented, on studying the va riation of morphological features (i.e., roughness and size of crystallites ) with thickness and growth rate.
