Energy per atom as a function of the area per atom for two-atom thick tin structures. All values are plotted with respect to the energy minimum of Sn-I. Gray curves represent a selection of structures obtained from the minima-hopping method that do not form a boundary for the energy curve. Thickness is measured as the vertical distance between the top- and bottom-most atoms of each structure. For reference, the buckled honeycomb mono-, AB bi- and ABA trilayers of stanene are located 296, 174 and 98 meV/atom above Sn-I, respectively, while bulk α-tin is merely 149 meV/atom below it
