Piezoresistivity in vapor-deposited diamond films
We report the observation of a very large piezoresistive effect in both polycrystalline and homoepitaxial chemical-vapor-deposited diamond films. The gauge factor for polycrystalline p-type diamond at 500 microstrains was found to be only 6 at room ambient, but increased rapidly with temperature, exceeding that of polycrystalline silicon (30) at 35 ‘C, and that of single-crystal Si (120) at 50 ...
متن کاملDiamond-like Carbon Films Deposited by Hydrocarbon Plasma Sources
Diamond-like carbon deposition techniques, characterization techniques and processing parameters, such as gas ratio, bias voltage, gas pressure, type of precursor gas used, temperature, gas total flow, substrate material, among others are reviewed. Mostly silicon substrates have been employed, but also metallic materials such as titanium and aluminum alloys or steels have been used as well. Imp...
متن کامل24 Tribology of Diamond , Diamond - Like Carbon , and Related Films
Diamond, diamond-like carbon (DLC), and other related materials (i.e., carbon nitride and cubic boron nitride [CBN]) are some of the hardest materials known and offer several other outstanding properties, such as high mechanical strength, chemical inertness, and very attractive friction and wear properties, that make them good prospects for a wide range of tribological applications, including r...
متن کاملCryogenic vacuum tribology of diamond and diamond-like carbon films
Friction measurements have been performed on microcrystalline, ultrananocrystalline, and diamond-like carbon DLC films with natural diamond counterfaces in the temperature range of 8 K to room temperature. All films exhibit low friction 0.1 in air at room temperature. In ultrahigh vacuum, microcrystalline diamond quickly wears into a high friction state 0.6 , which is independent of temperature...
متن کاملMorphological Characterization of Combustion Deposited Diamond Crystals and Films
Single crystals and polycrystalline diamond films of several thicknesses were deposited using oxygen/acetylene combustion flame technique. The substrate used was pure polycrystalline molybdenum subjected to mechanical polishing. Quality and microstructural characteristic of diamond produced were investigated using X-Ray diffraction, Raman Spectroscopy, Scanning and Transmission Electron Microsc...
