Present work investigates the annealing effects on MgO thin films deposited using e-beam evaporation method. MgO thin films of thickness 5 and 50 nm were evaporated from MgO-pellet in ultra-high vacuum (2×10-8 Torr). As deposited thin films exhibit coordination similar to MgO bulk as envisaged from near edge X-ray absorption fine structure measurements. As deposited films were annealed at 300, 400 and 500oC in open environment. Thickness of films remain unaltered with annealing within experimental error. Raman spectroscopic measurements further confirm the presence of bands associated with Mg-O bonding at such low thicknesses.

Keywords- e-beam evaporation, Annealing, Rutherford back scattering, Raman spectroscopy.
