JDCD05-001-006 10*10mm2*0.5mm electronic grade single crystal diamond,N content<100ppb, XRD<0.015º Thermal conductivity 1000-2200 for heat sink
Overview
CVD diamond has long been recognized as the ultimate material in a wide variety of applications due to its extreme qualities.
For diamond CVD atomic hydrogen plays a key role. It is obtained by dissociating hydrogen molecules (H2). So, what we need is a process gas that consists mainly of hydrogen (>90 %) and a gas activation, e.g. an intense plasma or a hot filament, to break up the hydrogen molecules. Atomic hydrogen is known to selectively etch graphite and to break up double bonds thus converting graphitic bonds into diamond bonds.
