Turner et al.’ used an infinite parallel-plate geometry, a Lennard- Jones 6-12 potential, and the Thompson distribution. They determined the spatial densities and average kinetic ener- gies of the sputtered particles, as functions of pressure and the distance from the cathode.

WebMar 11, 2024 · The basic presumption for the ta-C deposition is a sufficient energy of the film forming particles. Nearly all sputtered carbon particles leave the target as neutral atoms. Just above the target surface the energy distribution f(ε) of atoms sputtered in forward direction can be described by the Thompson distribution (see e.g. [9,10,11,12]) WebCathode sputtering [1, 2] is more frequently used in thin film technology than evaporation. The reasons for this are the following: - High melting material or dielectrics with a high frequency generator/source can be sputtered from a solid target. - Sputtering is a ballistic process in which the target remains relatively cold. hawaiian jasmine rice

When an electromagnetic wave is incident on a charged particle, the electric and magnetic components of the wave exert a Lorentz force on the particle, setting it into motion. Because the wave is periodic in time, so is the motion of the particle. Thus, the particle is accelerated and, consequently, emits radiation.
