Void formation in amorphous germanium due to high electronic energy depostition

Gärtner, K.; Johrens, J.; Steinbach, Tobias; Schnohr, Claudia; Ridgway, Mark C; Wesch, Werner


The effect of high electronic energy deposition in amorphous germanium has been studied experimentally by Au irradiation with ion energies of up to 185 MeV and different angles of incidence and by molecular dynamics computer simulations. In both cases, the energy deposition leads to void formation accompanied by strong swelling of the amorphous germanium. The simulation results prove that the formation of the voids is mainly based on a shock wave mechanism and the swelling is determined by the...[Show more]
