Zero-bias anomaly in two-dimensional electron layers and multiwall nanotubes [PDF]

, 2001
The zero-bias anomaly in the dependence of the tunneling density of states $\nu (\epsilon)$ on the energy $\epsilon$ of the tunneling particle for two- and one-dimensional multilayered structures is studied.

InAs/Si Hetero-Junction Nanotube Tunnel Transistors [PDF]

Scientific Reports, 2015
AbstractHetero-structure tunnel junctions in non-planar gate-all-around nanowire (GAA NW) tunnel FETs (TFETs) have shown significant enhancement in ‘ON’ state tunnel current over their all-silicon counterpart. Here we show the unique concept of nanotube TFET in a hetero-structure configuration that is capable of much higher drive current as opposed to ...

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

Advanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

Geometrical Dependence of High-Bias Current in Multiwalled Carbon Nanotubes

, 2003
We have studied the high-bias transport properties of the different shells that constitute a multiwalled carbon nanotube. The current is shown to be reduced as the shell diameter is decreased or the length is increased.

Liquid-induced damping of mechanical feedback effects in single electron tunneling through a suspended carbon nanotube [PDF]

, 2015
In single electron tunneling through clean, suspended carbon nanotube devices at low temperature, distinct switching phenomena have regularly been observed. These can be explained via strong interaction of single electron tunneling and vibrational motion

A Covalent 3D CNT@rGO Nano‐Hybrid for High‐Efficiency Conductivity in Lithium‐Ion Batteries

Advanced Science, EarlyView.
A facile one‐step CVD strategy achieves high‐yield (7692.31%) growth of CNTs on rGO, forming a covalently bonded 3D CNT@rGO hybrid. This structure enables multidirectional conductive networks in LiFePO4 cathodes, delivering superior rate performance, high ICE (99.88%), and 96.32% capacity retention after 300 cycles at 1 C.

Electrical conductivity of multi-walled carbon nanotubes-SU8 epoxy composites

, 2013
We have characterized the electrical conductivity of the composite which consists of multi-walled carbon nanotubes dispersed in SU8 epoxy resin. Depending on the processing conditions of the epoxy (ranging from non-polymerized to cross-linked) we ...

Revealing the electronic structure of a carbon nanotube carrying a supercurrent [PDF]

, 2010
Carbon nanotubes (CNTs) are not intrinsically superconducting but they can carry a supercurrent when connected to superconducting electrodes. This supercurrent is mainly transmitted by discrete entangled electron-hole states confined to the nanotube ...

Shaping electron wave functions in a carbon nanotube with a parallel magnetic field [PDF]

, 2018
A magnetic field, through its vector potential, usually causes measurable changes in the electron wave function only in the direction transverse to the field.
