Single crystal diamond CVD (chemical vapor deposition) refers to a type of diamond that is produced using the CVD process. In this process, a mixture of carbon-containing gases is decomposed under controlled conditions, resulting in the formation of a single crystal diamond layer on a substrate.

Single crystal diamond CVD is known for its exceptional hardness and thermal conductivity, which makes it useful for a range of industrial and scientific applications, such as cutting and grinding tools, heat spreaders, and optical components.

Compared to other forms of synthetic diamond, single crystal diamond CVD has a highly ordered crystal structure, which gives it improved physical and mechanical properties. This makes it a desirable material for a range of high-performance applications, where its hardness and thermal conductivity are important factors.

In summary, single crystal diamond CVD is a type of synthetic diamond that is produced using the CVD process and is characterized by its exceptional hardness and thermal conductivity. It has a wide range of applications in industries such as manufacturing, electronics, and optics.

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.
