Vibrational Tamm states at the edges of graphene nanoribbons
, 2010 We study vibrational states localized at the edges of graphene nanoribbons. Such surface oscillations can be considered as a phonon analog of Tamm states well known in the electronic theory.

Thermoelectric Conversion From Interface Thermophoresis and Piezoelectric Effects
Frontiers in Physics, 2022 Piezoelectric effect has proved itself to be a promising energy conversion mechanism that can convert mechanical energy into electricity. Here, we propose an indirect thermoelectric conversion mechanism based on a combination of the thermophoresis and ...

Phase coherent transport in graphene nanoribbons and graphene nanoribbon arrays [PDF]
Physical Review B, 2012 We have experimentally investigated quantum interference corrections to the conductivity of graphene nanoribbons at temperatures down to 20 mK studying both weak localization (WL) and universal conductance fluctuations (UCF). Since in individual nanoribbons at millikelvin temperatures the UCFs strongly mask the weak localization feature we employ both ...

Ab Initio Study of Ferroelectric Critical Size of SnTe Low-Dimensional Nanostructures
Nanomaterials, 2020 Beyond a ferroelectric critical thickness of several nanometers existed in conventional ferroelectric perovskite oxides, ferroelectricity in ultimately thin dimensions was recently discovered in SnTe monolayers.

Mechanical properties of graphene nanoribbons [PDF]
Journal of Physics: Condensed Matter, 2009 Herein, we investigate the structural, electronic and mechanical properties of zigzag graphene nanoribbons upon the presence of stress applying Density Functional Theory within the GGA-PBE approximation. The uniaxial stress is applied along the periodic direction, allowing a unitary deformation in the range of +/- 0.02%.

Peculiar Width Dependence of the Electronic Property of Carbon Nanoribbons
, 2006 Nanoribbons (nanographite ribbons) are carbon systems analogous to carbon nanotubes. We characterize a wide class of nanoribbons by a set of two integers $$, and then define the width $w$ in terms of $p$ and $q$.

Highly Stretchable MoS$_2$ Kirigami [PDF]
, 2015 We report the results of classical molecular dynamics simulations focused on studying the mechanical properties of MoS$_{2}$ kirigami. Several different kirigami structures were studied based upon two simple non-dimensional parameters, which are related ...
