✦ Synopsis

Large erosion ($1.1 Â 10 4 atoms/ion) of H from hydrogenated MCT wafers is observed due to the bombardment with 80 MeV Ni 9+ ions. The initial H areal concentration and hydrogen depletion rate is monitored by elastic recoil detection analysis. The ion-damaged zones from where depletion of H takes place have been calculated from fluence-dependent hydrogen areal content analysis. The results are explained on the basis of the thermal spike model of ion-solid interaction.
