Thermal Properties of CVD Diamond
One of many remarkable properties of diamond is its unsurpassed thermal conductivity. With a value of 2000 W/mK it exceeds that of copper by a factor of five. In contrast to metals, where heat is conducted by electrons, lattice vibrations are responsible for diamond's high thermal conductivity.
For thermal management applications, the outstanding thermal conductivity and diffusivity of diamond is an essential. Nowadays CVD diamond is used as submounts for high-power integrated circuits and laser diodes.
We have summarized the main properties of CVD diamond in our "CVD diamond booklet".
