Fig. 4From: Adsorption of Transition Metals on Black Phosphorene: a First-Principles Studya Local density of states (LDOS) of Pt and O2 molecules in Pt-phosphorene and O2-Pt-phosphorene systems and gas phase O2, respectively. b Charge density difference in the O2-(Pt-phosphorene) system; the yellow region (i.e., + 0.002 e/Å3) and the cyan region (i.e., − 0.002 e/Å3) correspond to the increase and the loss, respectively, of the electron densityBack to article page
