Conduction mechanisms in diamond-like carbon thin films prepared by PECVD method
The aim of this study is to prepare thin films of diamond-like carbon (a-C:H) and to determine the conduction mechanisms in the diamond-like carbon thin films. Diamond-like carbon (a-C:H) thin films were deposited on corning glass substrates using PECVD method. The samples were fabricated in Al/a-C:...
