Notes:
Photothermostimulated exoelectron emission (PTSE) is a relatively new method for studying structural imperfections in solids. The number of emitted electrons depends on the concentration of structural imperfections in a given material, like, for example, differently prepared amorphous metals of similar composition. Thin films of amorphous Cu–Zr have been prepared by e-beam codeposition and ion-beam mixing. A significantly higher electron emission intensity was found for ion-beam-mixed Cu–Zr compared to e-beam deposited films having similar composition. Calculated parameters from the PTSE spectra for the annealing reactions were also found to differ for the ion irradiated specimen. These observations suggest that both the number and type of long-lived nonequilibrium structural imperfections in amorphous Cu–Zr are affected by heavy-ion irradiation. © 1996 American Institute of Physics.
