摘要:
A plasma deposition apparatus includes a cathode assembly including a cathode disk and a water-coolable cathode holder supporting the cathode disk, an anode assembly including a water-coolable anode holder, a substrate mounted on the anode holder to serve as an anode, and a substrate holder mounting and supporting the substrate, and a reactor for applying a potential difference between opposing surfaces of the cathode assembly and the anode assembly under a vacuum state to form plasma of a raw gas. The cathode disk comes into thermal contact with the cathode holder using at least one of a self weight and a vacuum absorption force so as to permit thermal expansion of the cathode disk.

A method for making packets of nanostructures is presented. The method includes etching trenches in a silicon substrate. Nanostructures are grown in the trenches. The trenches are then filled with a filler material. Any filler and/or nanostructures material extending beyond the trench is removed. The silicon substrate is etched away, resulting in a nanopellet surrounding the nanostructures and wherein each nanostructures has a generally uniform length and direction. Nanostructures can comprise nanotubes, nanowires and nanofibers. The method eases the manipulation of nanostructures while providing geometrical uniformity.

摘要:
In the method for depositing a material in the absence of a positive column, a discharge is generated between a cathode and an anode disposed to face each other in a reaction chamber by applying a DC voltage therebetween, and introducing reaction gas into the reaction chamber, thereby depositing a material on a substrate mounted on the anode and serving as a part of the anode, wherein the deposition of the material on the substrate is performed under a state that a cathode glow and an anode glow exist in a form of thin layers coating respectively the surfaces of the cathode and the substrate, while a positive column does not exist or is so small as to be negligible.
