Abstract: 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.

Abstract: A grown single crystal diamond is polished using a non contact polishing technique, which leaves a residue on the diamond surface. In one embodiment, a wet chemical etch is performed to remove the residue, leaving a highly polished single crystal diamond surface. In a further embodiment, a colloidal silica solution is used in combination with rotating polishing pads to remove the residue. Both residue removing techniques may be used in further embodiments.

Abstract: N-V centers in diamond are created in a controlled manner. In one embodiment, a single crystal diamond is formed using a CVD process, and then annealed to remove N-V centers. A thin layer of single crystal diamond is then formed with a controlled number of N-V centers. The N-V centers form Qubits for use in electronic circuits. Masked and controlled ion implants, coupled with annealing are used in CVD formed diamond to create structures for both optical applications and nanoelectromechanical device formation. Waveguides may be formed optically coupled to the N-V centers and further coupled to sources and detectors of light to interact with the N-V centers.

Abstract: Monocrystalline diamond, adapted for use as in applications such as semiconductor devices, optical waveguides, and industrial applications, in the form of a single crystalline diamond structure having one or more diamond layers, at least one of which is formed by a CVD process. The diamond layers are “lattice-matched” or “lattice-mismatched” to each other to provide a desired level of strain.
