Cathode Sputtering,puttering process can be used to deposit large areas with very high lateral homogeneity. .- By ion bombardment, the substrates can be cleaned before coating, and the properties of the sputtered film can be influenced, e.g. adhesion, strength, structure, etc.

Physical Basics of Modern Methods of Surface and Thin Film Analysis,n diffraction LEED, reflection high energy electron diffraction RHEED) uses the periodic arrangement from surface atoms to the determination of the crystalline structure. The investigation of the electron work function also uses a collective characteristic, the potential jump at the surface.

Particle Beam Sources,e target atom. The energy exchange can be either elastic or inelastic, depending on the constituent particles and the energy of the ions. The momentum of an ion can be sufficient to dislodge a surface atom from a weakly bound position on the sample lattice and cause its relocation on the surface in a more strongly bound position (2).
