Two-dimensional (2D) nonlayered materials have recently provoked a surge of interest due to their abundant species and attractive properties with promising applications in catalysis, nanoelectronics, spintronics. However, 2D anisotropic growth still faces considerable challenges lacks systematic theoretical guidance. Here, we propose general thermodynamics-triggered competitive (TTCG) model providing multivariate quantitative criterion predict guide growth. Based on this model, design...
The intricate interplay between light and matter provides effective tools for manipulating topological phenomena. Here, we theoretically propose computationally show that circularly polarized holds the potential to transform axion insulating phase into a quantum anomalous Hall state in MnBi
The experimental realization of single-crystalline high-κ dielectrics beyond two-dimensional (2D) layered materials is highly desirable for nanoscale field-effect transistors (FETs). However, the scalable synthesis 2D nonlayered insulators currently limited by uncontrolled isotropic three-dimensional growth, hampering achievement simultaneous high dielectric constants and low trap densities small film thicknesses. Herein, we show a edge-seeded heteroepitaxial strategy to synthesize ultrathin...
Despite extensive research interests in perovskite oxides, low-energy consumption, nondestructive, and manoeuverable methods for phase transition oxides are still under exploration, the underlying mechanisms remain ambiguous. Here, optical susceptibility, including electron anharmonic phonon contributions, is used to evaluate Gibbs free-energy variations of ${\mathrm{Pb}\mathrm{Ti}\mathrm{O}}_{3}$ ${\mathrm{Ba}\mathrm{Ti}\mathrm{O}}_{3}$ terahertz irradiation. This corresponds an...
Abstract Optical resonator arrays are highly important fundamental units for integrated photoelectric devices, such as on‐chip logical circuits, high‐precision sensors, and laser displays. Whispering gallery mode (WGM) microrings (MRs) could reduce the optical losses provide a small volume, which is helpful integration of miniaturized devices. However, there still great challenge to produce pattern circular resonator. Here, facile poly(dimethylsiloxane) (PDMS) ring‐hole‐stamp confined...
During the shield construction of Harbin Subway Line No. 3 Project, average ground settlement exceeds warning value. In order to find cause and improve it, this paper establishes a prediction model analyse potential influencing factors based on Deep Belief Network (DBN) calculated correlation degree between through sensitivity analysis. It was found that permeability coefficients layer cutter head torque are main affecting settlement. Then, corresponding muck improvement measures were made...
Abstract A wide range of artificially twist‐stacked van der Waals materials offer versatile building blocks for quantum optoelectronic devices. Among these, twisted bilayer MoTe 2 has excellent optical properties in the near‐infrared and can be integrated with silicon photonics. While recent studies mainly focus on emission , a comprehensive investigation how Moiré superlattice affects phonon modes thin‐layer remains unexplored. These serve as indicators stacking configuration interface...
By using the basic principle of continuous damage mechanics as a reference, together with statistical strength theory based on Weibull distribution, new constitutive model fractured rock masses for deep underground engineering is proposed. In this model, definition fracture degree F t has been proposed first time, which can quantitatively describe fracturing process mass. Based results laboratory tests and numerical simulations mass specimens, different degrees verified. Moreover,...
The interfacial fracture of rock joints is an important although easily ignored issue in jointed engineering. To conduct this study, interface crack model was proposed. By analyzing the ratio stress intensity factor to toughness, mode studied. Based on Mohr-Coulomb criterion, criterion considering T-stress established. verify proposed laboratory and numerical tests were conducted. Finally, effect relative critical size α, internal friction angle φ cohesion c initiation comprehensively...
Fault current supplied by inverter interfaced distributed generation (IIDG) is different from that conventional power source, which will affect the trip of relay protection. So, research on optimization IIDGs in distribution network should take constraints protection into account. Firstly, definition maximum and minimum operation mode IIDG put forward, short-circuit calculation model also established. According to performance requirements network, access limit under conditions studied. Based...
