Motivated by recent experimental and theoretical research on a monolayer of boron atoms, borophene, the current–voltage characteristics of three different borophene sheets, 2Pmmn, 8Pmmn, and 8Pmmm, are calculated using density functional theory combined with the nonequilibrium Green’s function formalism.
