Abstract

MnS nano-crystalline films were formed on glass substrates by thermal evaporation technique at room temperature (300 K) and the films were annealed at 573 K. The films were characterized for composition, structure and surface morphology by using EDAX, XRD, SEM and AFM. The optical properties were studied by spectrophotometer. AFM studies showed that all the films were in nanocrystalline form with the grain size varying in the range between 30-32 nm and exhibited wurtzite structure. The lattice parameter and band gaps (3,842-3.916 eV) increase with increasing annealing temperature
