We report ballistic charge transport phenomena observed in carbon nano-peapod quantum dots. We find atom-like behaviors (shell filling) sensitive to applied back-gate voltages (V"b"g) by single electron spectroscopy. Doubly degenerate electronic leve

Anomalously high values of power α (1.6 < α < 12) are found in power laws in conductance versus energy relationships in carbon-nanotube peapod quantum dots, encapsulating a chain of C60 molecules. This power is controllable by the applied back gate

We report that entirely end-bonded multi-walled carbon nanotubes (MWNTs) can exhibit superconductivity with a transition temperature (T c ) as high as 12 K, which is approximately 30 times greater than T c reported for ropes of single-walled nanotube

We report successful observation of proximity-induced superconductivity in multi-walled carbon nanotubes (MWNTs) within a diffusive charge transport regime and also show enhancement of spin entanglement in coherent electron pairs of this MWNT as the

We fabricated NbN/multi-walled carbon nanotube (MWNT)/Al junctions using MWNTs standing in nano-porous alumina membranes. We observed a reduction in the resistance within the NbN superconducting energy gap voltage caused by Andreev reflection. Moreov

Electrode atoms are diffused, with only about 5% volume ratio, into the top end of multi-walled carbon nanotubes (MWNTs), standing in nanopores of porous alumina membranes. We find that diffusion of heavy materials leads to an anti-localization in th

Multi-walled carbon nanotubes (MWNTs), standing in nanoporous alumina membranes, are doped at one end by impurity atoms from electrode materials. Doping of the light-mass materials (carbon and aluminum) leads to weak localization in Altshuler–Arono

We report on two mesoscopic phenomena observable in nano-porous alumina films. One is Coulomb blockade associated with weak localization in an array of single nano-tunnel junctions/multi-walled carbon nanotubes (MWNTs), and the other is an abrupt mag
