Patent number: 8974599Abstract: Synthetic monocrystalline diamond compositions having one or more monocrystalline diamond layers formed by chemical vapor deposition, the layers including one or more layers having an increased concentration of one or more impurities (such as boron and/or isotopes of carbon), as compared to other layers or comparable layers without such impurities. Such compositions provide an improved combination of properties, including color, strength, velocity of sound, electrical conductivity, and control of defects. A related method for preparing such a composition is also described., as well as a system for use in performing such a method, and articles incorporating such a composition.Type: GrantFiled: October 29, 2004Date of Patent: March 10, 2015Assignee: SCIO Diamond Technology CorporationInventors: Robert C. Linares, Patrick J. Doering

Patent number: 8641999Abstract: Plasma assisted chemical vapor deposition is used to form single crystal diamond from a seed and methane. A susceptor is used to support the seed. Under certain conditions, crystalline grit is formed in addition to the diamond. The crystalline grit in one embodiment comprises mono crystals or twin crystals of carbon, each having its own nucleus. The crystals form in columns or tendrils to the side of the monocrystalline diamond or off a side of the susceptor. The crystals may have bonding imperfections which simulate doping, providing conductivity. They may also be directly doped. Many tools may be coated with the grit.Type: GrantFiled: July 11, 2005Date of Patent: February 4, 2014Assignee: SCIO Diamond Technology CorporationInventors: Patrick J. Doering, Alfred Genis, Robert C. Linares, John J. Calabria

Patent number: 8591856Abstract: An electrolytic cell includes a container for holding an electrolyte. A conductively doped single crystal diamond anode electrode is positioned to be disposed within the electrolyte, as is a conductive cathode electrode. Conductors are coupled to the electrodes for coupling to a power supply. An electrolyte inlet and an electrolyte outlet are coupled to the container for causing electrolyte to flow past the electrodes. The anode electrode is downstream from the cathode electrode in one embodiment, such that an electrolyte comprising water is purified by generation of oxygen and/or ozone.Type: GrantFiled: March 29, 2006Date of Patent: November 26, 2013Assignee: SCIO Diamond Technology CorporationInventors: Patrick J. Doering, Robert C. Linares, Alicia E. Novak, John M. Abrahams, Michael Murray

Patent number: 8553208Abstract: A system includes a radiation source to provide short wavelength light. A holder positions a table of a gemstone to receive the light. A detector is positioned to receive fluorescent light from the gemstone when the gemstone is a CVD grown gemstone.Type: GrantFiled: June 7, 2012Date of Patent: October 8, 2013Assignee: SCIO Diamond Technology CorporationInventors: Robert C. Linares, Patrick J. Doering

Patent number: 8514377Abstract: Diamonds may be identified as grown by the use of chemical vapor deposition. One or more diamonds may be placed on a surface and exposed to short wavelength light. Diamonds that fluoresce red may be identified as grown by the use of chemical vapor deposition. In some embodiments, the diamonds are cooled prior to exposure to the short wavelength light.Type: GrantFiled: March 12, 2012Date of Patent: August 20, 2013Assignee: SCIO Diamond Technology CorporationInventors: Robert C. Linares, Patrick J. Doering
