Web1 sep. 1999 · The energy distribution of the Ar + ions impinging on the cathode (target) is of crucial importance for the average sputtering yield. In order to calculate the energy distribution of Ar + ions falling on the cathode of a low pressure d.c. glow discharge in argon we have used a two-dimensional Monte Carlo code that simulates the ion … WebIons are directed to the substrate with an angular spread due to the ion thermal velocity at the sheath edge. The thermal velocity causes ions to have a velocity component parallel to the substrate surface while the sheath electric field accelerates the ion toward the substrate in the perpendicular direction. grant thornton llp delhi
