Effects of surface pretreatments on nucleation and growth of diamond films on a variety of substrates

Abstract

The effects of surface pretreatments on nucleation and growth of chemical vapor deposited diamond films were studied. The pretreatments included scratching with diamond grit, coating with a low vapor pressure, high thermal stability hydrocarbon oil, and coating with a 100–200-Å-thick layer of evaporated carbon. The effects of the treatments on carbide and noncarbide forming materials are described.
