Electrical and Mechanical Characteristics of Co-Doped and Ni-Doped Carbon Thin Films
Autor: Shigeru Umemura, Mitsunori Yabe, Shigeru Hirono
Publikováno v: Journal of The Surface Finishing Society of Japan. 61:379-383
To create conductive and wear-durable carbon thin films using metal doping, we deposited Co-doped and Ni-doped carbon thin films onto silicon substrates by RF sputtering. Then we evaluated the dopant concentrations, resistivity, scratch hardness, car
