In this work, we foresee the structure of a new class borophenes with smaller two-dimensional (2D) densities atoms than those explored so far for 2D boron crystals. Boron in porous tend to be five-coordinated contrast commonly investigated structures hexagonal holes which number nearest neighbors each atom varies from three six. High metallic character is usual feature borophenes, however, have...

Abstract Two dimensional quantum materials possessing Dirac cones in their spectrum are fascinating due to emergent low-energy fermions. In 8Pmmn borophene the cone is furthermore tilted, which a proxy for spacetime geometry, since future light-cone depends on underlying metric. Therefore it important understand microscopic origin of tilt. Here, based ab-initio calculations, we decipher atomist...

Electrochemically efficient electrode materials are required for clean energy storage in $\mathrm{Li}$ ion batteries. We predict two-dimensional hexagonal metal nitrides, borides, and phosphides (${\mathrm{Sc}}_{2}\mathrm{B}$, ${\mathrm{Sc}}_{2}\mathrm{N}$, ${\mathrm{Y}}_{2}\mathrm{B}$, ${\mathrm{Y}}_{2}\mathrm{N}$, ${\mathrm{Y}}_{2}\mathrm{P}$) evaluate the feasibility of experimental realizat...

In alignment with the efforts on miniaturizing components of electronic devices enhanced performance, we investigate a dielectric nanocapacitor (DNC) based metallic borophene electrodes separated insulating hexagonal boron nitride (h-BN) monolayers ($n=1--5$). The capacitive performance proposed DNC as function applied electric field ($\stackrel{P\vec}{E}$) and thickness material is examined by...
