Diamond has very high thermal conductivity and is considered to be an ideal thermal management material (including heat sinks, encapsulation materials, substrate materials, etc.) and is well suited for high power RF, optoelectronic and high voltage power semiconductor devices. Currently, we can provide 2.5 inch diameter homogeneous epitaxial single crystal diamond thermal management materials.
