Journal ArticleDOI
Carbon nanotube quantum resistors
TL;DR: The conductance of multiwalled carbon nanotubes (MWNTs) was found to be quantized and Extremely high stable current densities, J > 10(7) amperes per square centimeter, have been attained.
Journal ArticleDOI
Electrostatic deflections and electromechanical resonances of carbon nanotubes
TL;DR: The methods developed here have been applied to a nanobalance for nanoscopic particles and also to a Kelvin probe based on nanotubes, which indicates a crossover from a uniform elastic mode to an elastic mode that involves wavelike distortions in the nanotube.
Journal ArticleDOI
Giant osmotic energy conversion measured in a single transmembrane boron nitride nanotube
Alessandro Siria,Philippe Poncharal,Anne-Laure Biance,Rémy Fulcrand,Xavier Blase,Stephen T. Purcell,Lydéric Bocquet +6 more
TL;DR: The fabrication and use of a hierarchical nanofluidic device made of a boron nitride nanotubes that pierces an ultrathin membrane and connects two fluid reservoirs is described, which allows the detailed study of fluidic transport through a single nanotube under diverse forces, including electric fields, pressure drops and chemical gradients.
Journal ArticleDOI
A single nitrogen-vacancy defect coupled to a nanomechanical oscillator
O. Arcizet,Vincent Jacques,Alessandro Siria,Philippe Poncharal,Pascal Vincent,Signe Seidelin +5 more
TL;DR: In this paper, a single quantum system comprising a nitrogen-vacancy in diamond is coupled to a nanowire cantilever and magnetic fields are used to couple the spin and the oscillator enabling read-out of the nanometre-scale motion.
Journal ArticleDOI
Water-vapor effect on the electrical conductivity of a single-walled carbon nanotube mat
TL;DR: In this article, the influence of water vapor on the electrical resistance of a single-walled carbon nanotube mat (SWNTm) was investigated and it was shown that the sample exhibits a crossover from decreasing to increasing conductance versus water concentration in the surrounding atmosphere.
