Influences of Film Deposition Condition on Friction of Diamond-Like Carbon Film: A Theoretical Investigation

We theoretically investigated influences of film deposition condition on a friction of diamond-like carbon (DLC) film using our developed molecular dynamics method. The method can deal with chemical reactions on the basis of our original stochastic equation. DLC slab model was firstly constructed, a...
