  • Methods and apparatus for the production of group IV nanoparticles in a flow-through plasma reactor
    Patent number: 8471170
    Abstract: A plasma processing apparatus for producing a set of Group IV semiconductor nanoparticles from a precursor gas is disclosed. The apparatus includes an outer dielectric tube, the outer tube including an outer tube inner surface and an outer tube outer surface, wherein the outer tube inner surface has an outer tube inner surface etching rate. The apparatus also includes an inner dielectric tube, the inner dielectric tube including an inner tube outer surface, wherein the outer tube inner surface and the inner tube outer surface define an annular channel, and further wherein the inner tube outer surface has an inner tube outer surface etching rate. The apparatus further includes a first outer electrode, the first outer electrode having a first outer electrode inner surface disposed on the outer tube outer surface.
