![]() This intermediate phase is found to be determined by surface self-passivationĪnd the associated competition between A7- and A17-like bonding in the bulk. Transition from AB to AA stacked alpha-antimonene followed by a gradual At aĬritical thickness of ~4 nm, A17 antimony undergoes a diffusionless shuffle Revealed by real-time studies unraveling its thickness-driven transition to theĪ7 phase and the concomitant evolution of its electronic properties. Herein, we demonstrate that these two phases not onlyĬo-exist during the vdW growth of antimony on weakly interacting surfaces, butĪlso undertake a spontaneous transformation from the A17 phase to the On the other hand, bulk heavier elements are only Phase such as black phosphorus, and can transition to the layered rhombohedralĪ7 phase at high pressure. Light group VA elements are found in the layered orthorhombic A17 Valence electronic configuration, making them the only elemental materials toĬrystallize in layered van der Waals (vdW) and quasi-vdW structures throughout ![]() Botton, Oussama Moutanabbir Download PDF Abstract: Pnictogens have multiple allotropic forms resulting from their ns2 np3 Miwa, Søren Ulstrup, Aaron Bostwick, Eli Rotenberg, Michael S.
