Diamond are the hardest material and have the highest thermal conductivity in the world. With these important properties, diamonds have low thermal expansion and high electrical resistance. Because of the hardness, diamonds are very useful for abrasion, cutting, shaping, or finishing tools.
There are several ways to produce diamond films, using Chemical Vapor Deposition (CVD). And these films are expected to be used in a variety of applications, from cutting tools to wear-resistant parts. Diamond and diamond-like coating are also being used more in optical applications, , such as sunglasses, ophthalmic lenses, and infrared (IR) windows. New-generation electronic devices such as surface acoustic wave (SAW) and micro-electromechanical systems (MEMS) are also using diamond films.
