The superconducting proximity effect in single-walled carbon nanotubes connected to niobium electrodes was controlled with the use of nearby gates that tune the niobium-nanotube transparency. At 4.2 kelvin, when the transparency was tuned to be high, a dip in the low-bias differential resistance was observed, indicating a proximity effect mediated by(More)
High-quality single-walled carbon nanotubes (SWNTs) are synthesized by chemical vapor deposition (CVD) of methane on silicon-dioxide substrates at controlled locations using patterned catalytic islands. With the synthesized nanotube chips, microfabrication techniques are used to reliably contact individual SWNTs and obtain low contact resistance. The(More)
The basic structure of MEMS millimeter-wave phase shifters was consisted of a coplanar waveguide (CPW) transmission line periodically loaded with several thin metallic membranes. A new method was developed to obtain lower-loss microwave coplanar waveguide (CPW) by means of forming porous silicon (PS) on low-resistivity silicon wafer. The CPW fabricated on(More)
