Ion energy angular distribution

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. WebAngular distributions of currents and velocities (energies) of ions produced at various target irradiation angles and laser intensities ranged from 10 10 W/cm 2 to 10 17 W/cm 2 …
