Nano-spherical TiC particles are distributed on the diamond surface, which provides effective mechanical interlocking. The high TC of 800-Cu/55Dia is attributed to two factors: (1) formation of chemical bonding between the Cu matrix and the diamond, and this enables phonon transport from the Cu to the diamond; (2) formation of nanostructured TiC interfacial layer, and this enlarges the interfacial area that helps enhance the thermal transport, because the heat can also pass through the sidewalls of nanoparticles to across the interface … Note on the conduction of heat in crystals.

The purest natural diamond single crystals reported so far1,2 have a conductivity of 24–25 Wcm-1K-1 at 300K, compared to 4 for Cu and 1.5 for Si. V. I. Nepsha, V. R. Grinberg, Yu. Unusually high thermal conductivity in diamond films. G. S.

Ceramic materials with high thermal conductivity are mainly composed of oxides, nitrides, carbides, and borides, such as polycrystalline diamond ceramics, aluminum nitride, beryllium oxide, silicon nitride, and silicon carbide. The impact of deposition parameters on the thermal conductivity of cvd thin diamond films. Why Are Insulating Materials Often Multiphase? This property is at a maximum (meaning maximum thermal conductivity) with maximal isotopical purity (of either 12C or 13C), and at a minimum when there is a 50% mixture. Thermal conductivity of isotopically modified single crystal diamond. High temperature–high pressure (HTHP) method is proved to be favorable to attain high volume fractions of diamond particles in Cu/diamond composites, which guarantees the high thermal conductivities .

Wei, P. K. Kuo, R. L. Thomas, and R. W. Pryor. Diamond is highly crystalline in structure than other metals. Thus, the bottleneck for transferring heat away from the device is usually the thermal resistance at the interface between the device and the diamond, a subject which is in need of further research.8 The second category, the fabrication of devices within diamond, is hampered by the lack of a suitable electronic donor and, until recently, by the lack of CVD material of sufficient purity and crystalline perfection to satisfy even approximately the stringent electrical requirements for solid-state electronic materials.

One of the aims of this chapter is to suggest what might be expected when more measurements are available. T. R. Anthony. Phonon scattering in cvd diamond. Propagation of heat pulses in p-type germanium under uniaxial stress. Such high values of thermal conductivity have attracted attention to the possibility of using diamond for thermal management of electronic devices with high local power levels.4,5 The availability of polycrystalline diamond wafers made by chemical vapor deposition (CVD), of quality which now approaches that of the best single-crystal diamond, has opened the door to many imaginative applications of this new material.
