Diamond for thermal management

Diamond for thermal management

One of the remarkable properties of diamonds is that their incomparable thermal conductivity is five times that of copper. Heat is conducted by electrons in the metal, but lattice vibration is a key factor in diamond's high thermal conductivity due to extremely high arc discharge temperatures, the atomic hydrogen concentration therefore makes it easy to obtain diamond films with high thermal conductivity even with relatively high growth rates using DC ARC plasma jets. The thermal conductivity of optical quality single crystal diamond manufactured by our company is close to that of natural type IIA diamond, i. e. 2000W/mK. Thermal conductivity can be customized in the 800-2000W/MK Range and can therefore be subdivided into different quality grades to meet the different needs of our customers in non-application areas. Our company's single crystal diamond is used as the base of high power integrated circuits, the Gan (God) on the laser diode diamond and the radiator of the satellite electronic system.
