Electronic friction and liquid-flow-induced voltage in nanotubes [PDF]

, 2004
A recent exciting experiment by Ghosh et al. reported that the flow of an ion-containing liquid such as water through bundles of single-walled carbon nanotubes induces a voltage in the nanotubes that grows logarithmically with the flow velocity v0.

Atomic Scale Sliding and Rolling of Carbon Nanotubes [PDF]

, 1999
A carbon nanotube is an ideal object for understanding the atomic scale aspects of interface interaction and friction. Using molecular statics and dynamics methods different types of motion of nanotubes on a graphite surface are investigated.

A Numerical Study of Scaling Issues for Schottky Barrier Carbon Nanotube Transistors

, 2003
We performed a comprehensive scaling study of Schottky barrier carbon nanotube transistors using self-consistent, atomistic scale simulations. We restrict our attention to Schottky barrier carbon nanotube FETs whose metal source/drain is attached to an ...

A Fully Tunable Single-Walled Carbon Nanotube Diode

, 2010
We demonstrate a fully tunable diode structure utilizing a fully suspended single-walled carbon nanotube (SWNT). The diode's turn-on voltage under forward bias can be continuously tuned up to 4.3 V by controlling gate voltages, which is ~6 times the ...

Two-Stage Kondo Effect and Kondo Box Level Spectroscopy in a Carbon Nanotube

, 2010
The concept of the "Kondo box" describes a single spin, antiferromagnetically coupled to a quantum dot with a finite level spacing. Here, a Kondo box is formed in a carbon nanotube interacting with a localized electron.

dc Josephson Effect in Metallic Single-Walled Carbon Nanotubes

, 2007
The dc Josephson effect is investigated in a single-walled metallic carbon nanotube connected to two superconducting leads. In particular, by using the Luttinger liquid theory, we analyze the effects of the electron-electron interaction on the ...

Spectrometric and Voltammetric Analysis of Urease – Nickel Nanoelectrode as an Electrochemical Sensor

Sensors, 2007
Urease is the enzyme catalyzing the hydrolysis of urea into carbon dioxide andammonia. This enzyme is substrate-specific, which means that the enzyme catalyzes thehydrolysis of urea only.

Vacuum-field Rabi oscillations in atomically doped carbon nanotubes

, 2004
We report a strictly non-exponential spontaneous decay dynamics of an excited two-level atom placed inside or at different distances outside a carbon nanotube.

MOLECULAR ORDER AND DYNAMICS OF 5CB LIQUID CRYSTALS IN CONFINED SPACE – COMPUTER SIMULATION

TASK Quarterly, 2015
We studied the dynamical and structural properties of an important nematic 4-n-pentyl-4’-cyanobiphenyl (5CB) mesogen placed near carbon allotropes (graphene, nanotube), using modeling and molecular dynamics simulations (MD).
