摘要: The present invention provides a scalable method for achieving shape control of diamond micro-nanoparticles, comprising air oxidizing diamond micro-nanoparticles grown by chemical vapor deposition and/or diamond micro-nanoparticles grown by high pressure and high temperature. The present invention achieves the controllable morphology transformation of diamond micro-nanoparticles via air oxidation treatment. It has been demonstrated that a series of unique shapes, including “flower” shaped, “hollow” structured, “pyramid” patterned on the surface, and “boomerang” shaped, can be achieved by altering the air oxidation parameters, i.e., temperature and duration. The scalable production of these differently shaped diamond micro-nanoparticles represents a significant scientific breakthrough together with a high commercial value. The ability to produce diamond particles with desired shapes simply and cost-effectively will remove many obstacles to using diamonds for practical applications in nanophotonics, quantum computing, quantum optics, etc.

摘要: Disclosed are methods and systems for providing silicon carbide films. A layer of silicon carbide can be provided under process conditions that employ one or more silicon-containing precursors that have one or more silicon-hydrogen bonds and/or silicon-silicon bonds. The silicon-containing precursors may also have one or more silicon-oxygen bonds and/or silicon-carbon bonds. One or more radical species in a substantially low energy state can react with the silicon-containing precursors to form the silicon carbide film. The one or more radical species can be formed in a remote plasma source.

摘要: A plasma chemical vapor deposition system for growing diamond and diamond-like materials includes a process chamber having an exhaust port that is coupled to an input of a vacuum pump. A plasma generator generates a plasma in the process chamber. A cooling stage is positioned in the process chamber with a substrate holder positioned on a top surface that is configured to mount one or more substrates so they are exposed to the plasma generated by the plasma generator. The substrate holder defines a plenum having one or more portions. One or more pressure controllers are each configured to control a pressure in one of the first and second portion of the plenum so as to control a relative temperature of adjacent portions of the substrate holder.
