Monolayer\n                    <jats:italic>\u03b1<\/jats:italic>\n                    -AsN, a two-dimensional (2D) V\u2013V binary material with a wrinkled honeycomb structure, features better environmental stability (higher cohesive energy than black phosphorus, BP) and tunable electrical properties (unlike single-target VOC-sensing TMDs). It overcomes flaws of existing 2D sensors (BP\u2019s poor stability, TMDs\u2019 narrow selectivity) while retaining high surface-to-volume ratio, and shows superior adsorption efficiency and selectivity for alcohol VOCs versus BP and acetone-specialized Janus TMDs. However, its VOCs-sensing performance remains uninvestigated. This study employed density functional theory and nonequilibrium Green\u2019s function to systematically investigate the adsorption and sensing behaviors of monolayer\n                    <jats:italic>\u03b1<\/jats:italic>\n                    -AsN toward the five VOCs.

Among the tested VOCs, methanol and ethanol exhibited the highest adsorption energy and density (ethanol slightly higher), with ultra-low detection limits (7.69 \u00d7 10\n                    <jats:sup>\u2212<\/jats:sup>\n                    \u2074 p.p.b. for methanol and 4.88 \u00d7 10\n                    <jats:sup>\u2212<\/jats:sup>\n                    \u2075 p.p.b. for ethanol).
