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

To achieve conductive and wear-durable carbon thin films by metal doping, we deposited Au-, Pt-, and Pd-doped carbon thin films by RF sputtering, and evaluated the dopant concentrations, resistivity, and scratch hardness. Among the doped films, the P
