Non-centrosymmetric transition metal monopnictides, including TaAs, TaP, NbAs, and NbP, are emergent topological Weyl semimetals (WSMs) hosting exotic relativistic fermions. In this letter, we elucidate the physical origin of unprecedented charge carrier mobility which can reach $1\times10^{7}$ cm $^{2}$V$^{-1}$s$^{-1}$ at 1.5 K. Angle- temperature-dependent quantum oscillations, supported by density function theory calculations, reveal that NbP has coexistence p- n-type WSM pockets in...
SnSe is a promising thermoelectric material with record-breaking figure of merit. However, to date comprehensive understanding the electronic structure and most critically, self-hole-doping mechanism in still absent. Here we report highly anisotropic investigated by angle-resolved photoemission spectroscopy, which unique pudding-mould-shaped valence band quasi-linear energy dispersion revealed. We prove that p-type doping extrinsically controlled local phase segregation SnSe2 microdomains...
We report cathodic exfoliation of bulk SnSe for a high yield (>90%) synthesis sub-5 nm scale quantum dots.
The discovery of archetypal two-dimensional (2D) materials provides enormous opportunities in both fundamental breakthroughs and device applications, as evident by the research booming graphene, transition-metal chalcogenides, black phosphorus. Here, we report a new, large family semiconducting dialkali-metal monochalcogenides (DMMCs) with an inherent A2X monolayer (ML) structure, which two alkali sub-MLs form hexagonal close packing sandwich triangular chalcogen atomic plane. Such unique...
Negative magnetoresistance (NMR) induced by the Adler-Bell-Jackiw anomaly is regarded as most prominent quantum signature of Weyl semimetals when electrical field $E$ collinear with external magnetic $B$. In this article, we report universal NMR in nonmagnetic, centrosymmetric transition metal dipnictides MPn$_{2}$ (M=Nb and Ta; Pn=As Sb), which existence fermions can be explicitly excluded. Using temperature-dependent magnetoresistance, Hall thermoelectric coefficients Nernst Seebeck...
Layer-by-layer (LbL) assembly is widely applied as a coating technique for the nanoscale control of architecture and related properties. However, its translational applications are limited by time-consuming laborious nature process. Inspired blood-clotting process, herein, we develop shear-flow-driven LbL (SF-LbL) self-assembly approach that accelerates adsorption rate macromolecules mechanically configuring polymer chain via coil–stretch transition, which effectively simplifies speeds...
Monte Carlo simulations are carried out for Zn cluster supported on a suspended graphene to estimate the morphological evolution of following growth ZnO nanostructure. The metal–metal interactions modeled with tight-binding many-body potential and Lennard-Jones is used describe metal-carbon interactions. dynamic processes in temperature field decomposing drifting effects visualized through simulation. atoms make one regular atomic single layer sheet at relatively low temperature, which would...
We report extremely large positive magnetoresistance of 1.72 million percent in single crystal TaSb$_{2}$ at moderate conditions 1.5 K and 15 T. The quadratic growth (MR $\propto\,B^{1.96}$) is not saturating up to T, a manifestation nearly perfect compensation with $<0.1\%$ mismatch between electron hole pockets this semimetal. mechanism confirmed by temperature-dependent MR, Hall thermoelectric coefficients Nernst Seebeck, revealing two pronounced Fermi surface reconstruction processes...
Spin current generation and manipulation remain the key challenge of spintronics, in which relativistic spin-orbit coupling (SOC) plays a ubiquitous role. In this paper, we demonstrate that hidden Rashba spins nonmagnetic, centrosymmetric lattice multilayer ${\mathrm{SnSe}}_{2}$ can be efficiently activated by scattering introduced Se vacancies. Via vacancy scattering, conduction electrons with spin-momentum locked polarizations acquire out-of-plane magnetization components, effectively...

The normal subsidence monitoring technologies, used in civil engineering, are hard to apply ocean engineering. Because it is find a fixed reference for monitoring. A new method, which suitable of offshore platforms, proposed this paper. Firstly, the compression characteristic soil was analyzed and harms discussed. Based on analysis, method given. Finally, an real application shown. Some advanced measurement such as FBG strain techniques so on, were application. indicates that platforms.
Controlled formation and characterization of nickel clusters in the heterojunctions between carbon nanotube metal are reported via Monte Carlo simulations. Local structure cluster is analyzed quantitatively by common neighbor analysis technique. The cooling rate width gap where occupies both have important effects on morphology cluster.
