【Abstract】 Many properties of diamond (e.g. its physical hardness, high Young’s modulus, high tensile yield strength, chemical inertness, low coefficient of friction and high thermal conductivity) make it an excellent material for micromechanical device applications. It has been established that diamond films have piezoresistivity. This property enables diamond films to be used in the field of pressure sensor applications. This paper studies electrical characteristics of ohmic contacts and thermal-sensitive charactnstics and how resistance changes in response to pressure applied on diamond films. The results show that diamond films can be used to make sensors for high temperature.更多还原
