چکیده
The research of two-dimensional (2D) materials with atomic-scale thicknesses and unique optical properties has become a frontier in photonics electronics. Borophene, newly reported 2D material provides novel building block for nanoscale devices. We present simple borophene-based absorption structure to boost the light-borophene interaction via critical coupling visible wavelengths. proposed consists borophene monolayer deposited on photonic crystal slab backed metallic mirror. numerical simulations theoretical analysis show that light can be remarkably enhanced as high 99.80% mechanism guided resonance, polarization-dependent behaviors are demonstrated due strong anisotropy borophene. also examine tunability by adjusting carrier density lifetime borophene, air hole radius slab, incident angle polarization angle. access flexible effective manipulation interactions visible, shows good prospect future electronic

MoS2 Surface Structure Tailoring via Carbonaceous Promoter
Atomically thin semiconducting transition-metal dichalcogenides have been attracting lots of attentions, particularly, molybdenum disulfide (MoS2) monolayers show promising applications in field effect transistors, optoelectronics and valleytronics. However, the controlled synthesis of highly crystalline MoS2 remain a challenge especially the systematic approach to manipulate its structure and ...
متن کاملPore-scale flow simulation in anisotropic porous material via fluid-structure coupling
This paper describes a novel hybrid method for fluid simulation of saturating anisotropic porous material via fluid-structure coupling. Our framework employs particle finite element method (PFEM) that not only adopts Lagrangian scheme to model the motion of freely-moving particles, but also produces the extended Delaunay Tessellation to furnish the governing equations with FEM discretization. W...
متن کاملA critical review on structure-soil-structure interaction
The purpose of this paper is to review computational methods in structure-soil-structure interaction. As a result of globalization, buildings are located close to each other. This issue happens especially in big cities, making the study of structure-soil-structure interaction as an essential part of structural design process. The effect of soil medium, on which the building structure stands, es...
