2.01 ct D SI1 VG EMERALD HPHT diamond
Lab grown diamonds, also known as synthetic diamond , man made diamond or cultured diamonds, are grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust.   Lab grown diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties.

big size Semiconductor Polycrystalline Cvd Diamond Wafer Polycrystalline thermally conductive cvd diamond film

Diamond film refers to a diamond film artificially synthesized by low-pressure or atmospheric pressure chemical vapor deposition (CVD) method. There are two main methods for preparing diamond films: thermal chemical vapor deposition (TCVD) and plasma chemical vapor deposition (PCVD).

Polycrystalline CVD diamond

 

polycrystalline CVD (chemical vapour deposition) synthetic diamond products are manufactured by a chemical vapour deposition (CVD) process and are subject to tightly controlled growth conditions during manufacturing and equally stringent quality control procedures.

 

 

CVD Diamond for thermal applications:
One of many remarkable properties of diamond is its unsurpassed thermal conductivity. 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 the high thermal conductivity of diamond.   
 
Thermal conductivity can be tailored within the range of 1000-1800 W/mK to enable matching cost/performance to the needs of the application.
Nowadays CVD diamond made by our Laboratory is used as  mounts for high-power integrated circuits and laser diodes.
