Schematic representation of structure and atomic arrangement of the layered “beyond graphene” materials which are the focus of the present work: a, e, i Top view of the ball and stick atomic models of phosphorene, MXene, and TMD (MoSe₂), respectively. b, f, j Side view of the atomic models showing the layered structure of phosphorene, MXene, and TMD (MoSe₂), respectively. SEM images showing the characteristic layered structure of c, g, k SEM images showing the characteristic layered structure of phosphorene, MXene, and TMD (MoSe₂), respectively. d, h, i HRTEM image demonstrating the arrangement of the atoms in the lattice for phosphorene, MXene, and TMD (MoSe₂), respectively [24, 62–71].
