Geometric effects in the electronic transport of deformed nanotubes

F Santos, S Fumeron, B Berche, F Moraes - Nanotechnology, 2016 - iopscience.iop.org
Quasi-two-dimensional systems may exibit curvature, which adds three-dimensional
influence to their internal properties. As shown by da Costa (1981 Phys. Rev. A 23 1982–7) …

Geometry-driven shift in the Tomonaga-Luttinger exponent of deformed cylinders

Curvature-induced bound states and coherent electron transport on the surface of a truncated cone

L Du, YL Wang, GH Liang, GZ Kang, XJ Liu… - Physica E: Low …, 2016 - Elsevier
We study the curvature-induced bound states and the coherent transport properties for a
particle constrained to move on a truncated cone-like surface. With longitudinal hard wall …

Torsion-induced persistent current in a twisted quantum ring

H Taira, H Shima - Journal of Physics: Condensed Matter, 2010 - iopscience.iop.org
We describe the effects of geometric torsion on the coherent motion of electrons along a thin
twisted quantum ring. The geometric torsion inherent in the quantum ring triggers a quantum …

Pressure‐induced structural transitions in multi‐walled carbon nanotubes

H Shima, M Sato - physica status solidi (a), 2009 - Wiley Online Library
We demonstrate a novel cross‐sectional deformation, called the radial corrugation, of multi‐

Electronic states on the helicoidal surface

B Jensen - Physical Review A—Atomic, Molecular, and Optical …, 2009 - APS
It is shown that free electrons on the helicoidal surface are affected by an effective potential,
which vanishes in the s channel and gives rise to both metastable as well as stable bound …
