Abstract: A method has been developed of synthesizing Y-SWNTs with controlled density, position, and growth direction. The process includes patterning a substrate with a solvent solution of catalyst metal ions, dopant metal ions and metal oxide ions, having in a molar ratio of catalyst to dopant in the range of 0.1 to 0.5 moles of catalyst metal per mole of dopant metal, prior to heating to 600-1200° C. with a flow of hydrocarbon gas. A Y-SWNT can be used as a building component of nanoscale two- and three-terminal electronic devices, such as interconnects, diodes, and transistors. This development has a profound impact on nanoscale semiconductor industry, since it is certain that the market share of nanoscale devices using Y-SWNTs will be increased to a great extent.

Abstract: A rotary transformer assembly of a rotary head drum device, comprising a plurality of concentric circular shielding walls for isolating adjacent pairs of channels from each other so as to prevent a leakage of electromotive force between the pairs of channels and a plurality of concentric circular slots for receiving the ends of the shielding walls so as to isolate the adjacent pairs of channels from each other in combination with the shielding walls. The shielding walls are provided at one of the transformer rotor and the transformer stator as protruding at the outer side of the outermost channel, at the inner side of the innermost channel and at a position between each adjacent pairs of channels. The slots are provided at portions, corresponding to the shielding walls, of the other of the transformer rotor and the transformer stator.
