Dr.Yuan Chat Diamonds: CVD Diamonds for Industrial Use
Mankind has always hoped to use lab-grown diamonds for various industrial purposes. Up to now, only the hardness of the small particles of diamond abrasive grown by HPHT has been used as a super-hard material to make various abrasive tools for grinding and polishing. However, in the aspects of sound, optic, chemical, electron, thermal, a large area of single crystal diamond flake materials are still being developed and not actually used.
It was first grown into a polycrystalline diamond plate or diamond film by CVD several decades ago. Because the surface is a rough polycrystalline structure and it is difficult to polish, it has not been widely used. After about year 2000, it began to grow in a new way. Single crystal CVD lab-grown diamonds grow upward on flat seed plates and can be made into larger areas, but their cost is too high to be mass-produced, and they are used in commercial industry at a low enough price. So, it hasn't really been used extensively so far.

Our research direction:
Boron-doped CVD polycrystalline films and sheets are used as electrodes for water treatment, as water purification treatment, eliminating organic organisms and heavy metals in the water, purification of precious metal tailings, desalination of seawater, refining valuable metals in seawater, and decomposing water into hydrogen and Oxygen can decompose a large amount of deuterium and tritium by increasing the voltage, which can be used as a raw material for nuclear fusion.
Diamond soaking plate has great demand for heat dissipation of high-power chips and electronic devices, but the current price is too high. Only military products have a small demand. The price must be reduced to 1/10 of the current price before commercial products are Affordable to use.
Diamond LED ultrashort wave PN junction emits light, diamond wafer is grown on diamond with positive and negative semiconductors to produce 215nm LED light, which is used for ultra-high-power LED light, making sterilization tools, ultra-strong lasers for cutting tools, long-distance killing weapons, and making the most critical light source for lithography machines for the semiconductor industry.
Diamond wafer splicing method makes CVD large-area single crystal wafers. As LED and semiconductor chip substrates, it can completely solve the heat dissipation problem and utilize the super excellent physical and chemical properties of diamond, which will make the human semiconductor industry to enter the ultimate fourth-generation wafer material, solves the problem that mankind has reached the limit of using silicon wafers.
The commercial use of CVD diamonds in industry will gradually mature in the next few years, and the demand will be ten to one hundred times the share of jewelry diamonds. The lab-grown diamonds, especially CVD diamonds, is now a maturing sunrise enterprise. In the future, there is great room for development in jewelry diamonds and industrial heat dissipation, semiconductors, high-end electronics, autopilots, quantum computers, high-end lasers..., will be the beginning of a new era, which will last for more than a hundred years.
