Microstructure and Physical Properties of Sputtered Metal Containing Nanocrystalline Structured Carbon Coatings

Autor: Sung I. Kim, Jeon G. Han

Publikováno v: Journal of the Korean institute of surface engineering. 40:59-62

Metal containing hydrogen free nanocrystalline structured carbon (Me:nc-C) films were synthesized by closed-field unbalanced magnetron sputtering system (CFUBM). The aim of this study was to determine the relationship between the microstructure and p
