The improvement of the adhesion - connection between different (inorganic/organic) materials and the growth of thin films aiming towards the treatment of surfaces and the production of systems and nano-devices with desirable and functional properties (low friction, high hardness - reflectivity - resistance in erosion - barrier properties etc.), has a high scientific and technological interest, since it covers a wide area of applications (blades, optical systems, photovoltaics, microelectronics, displays, flexible packaging, biomaterials). The type of bonding with which two materials are connected, depends by their type, the chemical bond, the bonding (amorphous, crystalline), their surface energy, the atomic process during contact, which determine also their auto-organisation. The confrontation that of this subject is particularly complicated since these materials, usually in nanoscale, are amorphous, and cannot be characterized with conventional techniques. The surface of one must be modified atomically or a intermediate layer should be used so that the contact between them can be is optimised, and in combination with suitable nanostructures (e.g films) to achieve the desirable and functional properties of the system.
