Intimate relationship between structural deformation and properties of single-walled carbon nanotubes
(Cambridge, 2002)
Carbon nanotubes continue to surprise scientists with their novel properties. Recently we have discovered many intimate relationships between structural deformation and the properties of single-walled nanotubes (SWNT), ...
First-principles study of superlow friction between hydrogenated diamond surfaces
(ASME, 2005)
Attractive interaction between two clean diamond(001) slabs turns repulsive upon the hydrogenation of surfaces. Even under high loading forces, this repulsive interaction prevents the sliding surfaces from being closer to ...
Functionalized carbon nanotubes and device applications
(IOP, 2004)
Carbon nanotubes, in which the two-dimensional hexagonal lattice of graphene is transformed into a quasi-one-dimensional lattice by conserving the local bond arrangement, provide several structural parameters for engineering ...
Quantum transport through one-dimensional aluminum wires
(American Vacuum Society, 2002)
Quantum conductance in narrow channels has been well understood by using the two-dimensional
electron gas, a model system which has been realized in semiconductor heterojunctions. An essential
property of this electron ...
Stable, one-dimensional suspended and supported monatomic chains of pnictogens: a metal–insulator framework
(Royal Society of Chemistry, 2019-06)
Group-VA elements P, As, Sb, and Bi can construct free-standing, stable zigzag monatomic chain structures, which show unusual properties. They are normally semimetals with bands crossing at the Fermi level, but a very ...
Mechanical and electrical monitoring in the dynamics of twisted phosphorene nanoflakes on 2D monolayers
(American Chemical Society, 2019)
We investigated the rotational and translational dynamics of hydrogen-passivated, black phosphorene and blue phosphorene nanoflakes of diverse size and geometry anchored to graphene, black phosphorene, blue phosphorene, ...
Glycine self-assembled on graphene enhances the solar absorbance performance
(Elsevier, 2018)
Despite its high solar absorbance and surface coating abilities, pristine graphene as a semimetal is not
promising for photovoltaic applications. In this study, we predict that Glycine (Gly), an amino acid, which
is ...
Novel metallic clathrates of group-IV elements and their compounds in a dense hexagonal lattice
(American Chemical Society, 2019)
Further, to recently introduced metallic NaSi6 and Si6 clathrate structures, we show that not only Si but also other group-IV elements, such as C, Ge, and Sn, can form stable and metallic clathrate structures with open ...
Deformed octagon-hexagon-square structure of group-IV and group-V elements and III-V compounds
(American Physical Society, 2019)
We report the prediction of a two-dimensional (2D) allotrope common to group-IV and group-V elements and III-V compounds, which consist of two nonplanar atomic layers connected by vertical bonds and form deformed octagon, ...
Two-dimensional pnictogens: a review of recent progresses and future research directions
(American Institute of Physics, 2019)
Soon after the synthesis of two-dimensional (2D) ultrathin black phosphorus and fabrication of field effect transistors thereof, theoretical studies have predicted that other group-VA elements (or pnictogens), N, As, Sb, ...
