Proximity-induced superconductivity and its re-entrance effect in niobium/multi-walled carbon nanotube junctions
نویسندگان
چکیده
We report on an experimental study of diffusive transport near the highly transparent interface of niobium(Nb)/multi-walled carbon nanotube (MWNT) junctions realized by utilizing the nanopores of alumina membranes. In the magnetic-field dependence of observed conductance increase, the transition temperatures vs nanotube length diagram, and the zero-bias conductance peak, we observed proximityinduced superconductivity with an onset temperature of T 1⁄4 9 K at the highest case and its re-entrant conductance. These phenomena are manifestations of the extremely large diffusion constant of the Cooper pairs in our MWNTs. q 2003 Elsevier Science Ltd. All rights reserved.

Carbon nanotube Josephson junctions with Nb contacts
We report on the preparation of carbon nanotube Josephson junctions using superconducting electrodes made of niobium. Gate-controllable supercurrents with values of up to 30 nA are induced by the proximity effect. The IV curves are hysteretic at low temperature and the corresponding switching histograms have a width of 0.5%–2%. An on-chip resistive environment integrated in the sample layout is...
متن کاملGate-Controlled Superconducting Proximity Effect in Carbon Nanotubes.
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 Andreev reflection. When the transparency wa...

Introduction: Trichloroethylene (TCE) is an industrial solvent which is often used as a degreaser for metal parts. Due to adverse health effects and carcinogenic properties of this solvent, knowing its concentration in the workplace atmosphere is really crucial. Nowadays, carbon nanotubes with high efficiency are being used for sampling of this chemical. Method:</stron...
متن کاملFractal-Like Kinetics Study of Adsorption on Multi-walled Carbon Nanotube
The fractal degree of adsorption on the multi-walled carbon nanotube has been investigated. The fractal-like Langmuir kinetics model has been used to obtain the fractal degree of ion adsorption on multi-walled carbon nanotube. The behavior of the fractal-like kinetics equation was compared with some famous rate equations like Langmuir, pseudo-first-order and pseudo-second-order equations. It is...
متن کاملElectronic structures of boron-doped single-walled carbon nanotube
Since the discovery of the superconductivity in boron-doped diamond [1], the carrier doping, especially boron doping in carbon materials attracts much attentions. For the carbon nanotube, however, the effect of boron doping as well as the possibility of the superconductivity [2] have not been well understood yet. Thus, we systematically study the boron-doped single-walled zigzag carbon nanotube...
