Investigation of the magnetic and transport properties of single-walled small-diameter carbon nanotubes embedded in a zeolite matrix revealed that at temperatures below 20 kelvin, 4 angstrom tubes exhibit superconducting behavior manifest as an anisotropic Meissner effect, with a superconducting gap and fluctuation supercurrent. The measured superconducting characteristics display smooth temperature variations owing to one-dimensional fluctuations, with a mean-field superconducting transition… 
Current instability and diamagnetism in small-diameter carbon nanotubes
We investigate the electronic instabilities in carbon nanotubes of short radius, looking for the breakdown of the Luttinger liquid regime from the singular behavior of the charge stiffnesses at low
Suppression of electron?electron repulsion and superconductivity in ultra-small carbon nanotubes
Recently, ultra-small diameter single wall nanotubes with diameter of ~0.4 nm have been produced and many unusual properties were observed, such as superconductivity, leading to a transition
Zero-bias anomaly and possible superconductivity in single-walled carbon nanotubes
We report measurements of field-effect transistors made of isolated single-walled carbon nanotubes contacted by superconducting electrodes. For large negative gate voltage, we find a dip in the
Superconductivity in Bundles of Double-Wall Carbon Nanotubes
Electrical and thermal specific heat measurements that show superconductivity in double-wall carbon nanotube (DWCNT) bundles show an intrinsic superconducting transition below 6.8 K for one particular sample, which opens the exciting possibility of tuning the Tc through the application of a gate voltage.
Superconductivity in Entirely End-Bonded Multi-Walled Carbon Nanotubes
We report that entirely end-bonded multi-walled carbon nanotubes (MWNTs) within Tomonaga-Luttinger liquid (TLL) states at high temperatures can show superconductivity with the transition temperature
Superconductivity in 4-Angstrom carbon nanotubes--a short review.
We give an up-to-date review of the superconducting phenomena in 4-Angstrom carbon nanotubes embedded in aligned linear pores of the AlPO(4)-5 (AFI) zeolite, first discovered in 2001 as a fluctuation
Paraconductivity in carbon nanotubes
We report the calculation of paraconductivity in carbon nanotubes above the superconducting transition temperature. The complex behavior of paraconductivity depending upon the tube radius,


Superconductivity at 18 K in potassium-doped C60
THE synthesis of macroscopic amounts of C60 and C70 (fullerenes)1 has stimulated a variety of studies on their chemical and physical properties2,3. We recently demonstrated that C60 and C70 become
Mono-sized single-wall carbon nanotubes formed in channels of AlPO4-5 single crystal
An alternative approach to the synthesis of mono-sized and parallel-aligned single-wall carbon nanotubes (SWCNs) is reported. The SWCNs are formed in 0.73 nm sized channels of microporous
Superconductivity at 33 K in CsxRbyC60
THE synthesis of macroscopic quantities1,2 of the fullerenes C60 and C70 has led to discoveries of several unusual properties3–10, in particular the high conductivity3 and superconductivity4–6 of
Superconductivity at 52 K in hole-doped C60
This work uses the technique of gate-induced doping in a field-effect transistor configuration to introduce significant densities of holes into C60, and observes superconductivity over an extended range of hole density.
Materials science: Single-walled 4 Å carbon nanotube arrays
The smallest carbon nanotubes possible are described, prepared by the pyrolysis of tripropylamine molecules in the channels of porous zeolite AlPO4-5 (AFI) single crystals.
