DOI: 10.1103/physrevb.101.125408
Abstract: We predict a two-dimensional monolayer polymorph of boron nitride in an orthorhombic structure (oB2N2) using first-principles calculations. Structural optimization, phonon dispersion, and molecular dynamics calculations show that o-B2N2 is thermally and dynamically stable. o-B2N2 is… read more here.

Abstract: Electromagnetic perfect absorption entails impedance-matching between two adjacent media, which is often achieved through the excitation of photonic/plasmonic resonances in structures such as metamaterials. Recently, super absorption was achieved using a simple bi-layer configuration consisting… read more here.
