Volume 3, Issue 2, Page 112-117, Year 2012 | DOI: 10.5185/amlett.2012.1307

Keywords: MgO; atomic force microscopy; X-ray absorption spectroscopy

Abstract: 

Present work reports 200 MeV Ag15+ irradiation induced effects on the surface morphology, grain size and local electronic structure in MgO thin films deposited by e-beam evaporation under ultra High vacuum.  The grain size was found to decrease from 37 nm (pristine film) to 23 nm for the sample irradiated with fluence of 1×1012 ions/cm2 and thereafter it increases upto fluence of 5×1012 ions/cm2. Similar changes with ion fluence were also observed for surface roughness. Shifting and disappearance of peaks in X-ray absorption spectra with irradiation shows the electronic structure modification after irradiation. The detailed analysis of observed results has been done on the basis of existing theories. Copyright © 2012 VBRI Press.
