Ripple is a common deformation in two-dimensional materials due to localized strain, which expected greatly influence the physical properties. The effects of ripple MoS2 layer on their physics, however, are rarely addressed experimentally. We here grow atomically thin nanostructures by employing vapor phase deposition method without any catalyst and observed ripples nanostructures. exhibit quasi-periodical structures surface. heights vary from several angstroms tens nanometers wavelength...
The dynamics of an inverted flexible plate with a free leading-edge and fixed trailing-edge in uniform flow has been studied numerically by immersed boundary-lattice Boltzmann method for the fluid finite element deformation. Mechanisms underlying fluid-plate system are elucidated systematically. A series distinct states deformation motion identified can be described as straight, flapping, deflected, deflected-flapping, asymmetric-flapping states. Which state to occur depends mainly on...
Using the coordination‐constrained searching strategy implemented in RG 2 software, a novel metastable silicon crystal named oP16‐Si, which hosts lower energy compared to previously synthesized Si 24 is reported. The first‐principles calculations further confirm its dynamic, mechanical, and thermodynamic stabilities, indicating potential for experimental synthesis. corresponding characterization of Raman spectrum eigenvibration vectors calculated identification as well. analysis mechanical...
Learning tool use from a single human demonstration video offers highly intuitive and efficient approach to robot teaching. While humans can effortlessly generalize demonstrated manipulation skill diverse tools that support the same function (e.g., pouring with mug versus teapot), current one-shot imitation learning (OSIL) methods struggle achieve this. A key challenge lies in establishing functional correspondences between test tools, considering significant geometric variations among...
Herein, two silicon allotropes (CMMM‐Si 20 and CCCA‐Si 18 ) with excellent photoelectronic properties are proposed, based on first‐principles calculations. Through the Heyd–Scuseria–Ernzerhof‐based band of CMMM‐Si , it is revealed that they direct bandgap semiconductors fundamental bandgaps 0.6373 0.7704 eV, respectively, robust against strain. Furthermore, found both exhibit stronger light absorption capacity than diamond (cd‐Si) in visible region. In results, shown low‐energy meta ‐stable...
Recently, constructing three-dimensional materials through two-dimensional is attracting research attention in both experiment and theory due to the properties beyond ordinary 3D materials. In this work, we propose a carbon allotrope by interpenetrating α-graphyne sheets with van der Waals interactions study its structural electronic first-principles calculations tight-binding methods. Our show that energy of interpenetrated slightly lower than nanosheet weak interactions, dynamical...
Using the classical molecular dynamics and simulated annealing techniques, we show that monolayer graphene nanoribbons (GNRs) on 6H-SiC(0001) surface form atomic scale rippled structures. From analysis of configurations, two different types structures in GNRs can be identified, namely, periodic structure at room temperature or even lower temperatures random ripples high temperatures. The dependence microscopic roughness size are studied through analyzing covalent bonding inhomogeneities...
The growth process of graphene structure on 6H-SiC(0001) surface has been studied using the classical molecular dynamics simulation and simulated annealing technique. Effects temperature coverage carbon atoms formation have investigated. We found that two layers subsurface after sublimation Si undergo a transformation from diamondlike phase to graphenelike at above 1500K. This is in good agreement with experimental observations. also strongly depends number layers. Two result large clusters...
In order to optimize the structure of a subway shield tunnel, minimize injuries, and avoid potential safety hazards, lateral convergence deformation tunnels should be predicted. terms accuracy stability, existing prediction models perform poorly in obtaining value non-stationary small-sized sample tunnel. this paper, model tunnel based on Kalman algorithm is constructed filtering theory. The efficient, adaptive, robust can accurately predict Taking horizontal diameter 200-ring segment...
