Threshold energy for sputtering and its dependence on angle of incidence
The sputtering yield at low energies and at various angles of incidence has been investigated by computer simulation with the TRIM.SP program and compared to experimental data available. The question of the sputtering threshold energy is discussed in detail, and the processes responsible for sputtering at these low energies are studied. It is shown that for heavy ion sputtering the threshold depends on the angle of incidence. Analytical equations are derived which demonstrate that the inelastic energy loss plays an important role in the threshold for heavy projectiles.
