Irradiation effects on microstructure change in ...
2 using an ionbeamassisted deposition system (Mill Lane engineering, Lowell, MA) at the Nanotechnology Laboratory at the University of Nebraska Medical Center [10]. The thin films were then irradiated with MeV Au+ ions up to fluence of 1015 ions cm 2 at temperatures of 300 and 400 K. The ion flux was kept constant during the irradiation
