Driven in parallel by the demands of technology and the inquisitiveness of basic science/engineering, the last decade has brought an explosion in the development of new materials. In this effort, design and synthesis of surface layer and thin film systems present particular advantages and interest since several material properties are surface-sensitive and applications demand materials with novel properties for miniaturized, small-scale components and devices (MEMS, NEMS, etc.). These needs led to research in functionally gradient, multifunctional and self-organized nanostructured thin films. An overview of research activities in the Surface and Nanostructure Engineering Laboratory (SaNEL) will be presented, involving: (i) development of functionally gradient surface layers by utilizing intensified plasma-assisted processing (a novel technique developed in our laboratory); (ii) Me-containing nanocomposite diamondlike carbon films with functionally gradient interfaces; (iii) multifunctional (mechanical, tribological, magnetic, etc.) metal/ceramic nanocomposite and multilayered thin films, and (iv) epitaxially grown, self-organized oxide, nanostructured thin films with high potential for electronic applications.
