Moreover, the doping gap can be effectively modulated in each case by applying an external perpendicular electric field. The optical absorption of blue phosphorene can be considerably enhanced in a broad spectral range through the adsorption of CCO, F4-TCNQ, and F6-TNAP molecules, suggesting potential of the doped materials in the field of renewable energy. © 2019 IOP Publishing Ltd.absorptionblue phospherenedoping gapfirst-principlesmolecular dopingjournal article10.1088/1361-648X/ab46282-s2.0-85075813376
