Fig. 4: Optimal prototype host.
From: Pettifor maps of complex ternary two-dimensional transition metal sulfides
Optimal prototype for TM pairs. The colourcode shows the energy cost at each end of the window, in eV/site. The scale is reported in the first colorbar on the right. The energy cost of the mark refers to the end of the metastability window closer to the MS2 indexed by the x-axis. The size of the marker encodes the metastability window size, as reported by the legend on the far right. The edge colour of each marker indicates whether the optimal prototype is the ground state of both (green), one (grey) or neither (red) the pristine TMDs comprising the (M: Q)S2 mixture. Marker-prototype correspondence is reported in the legend at the bottom right. Markers on the diagonal show the GS prototype of the corresponding metal disulfide. Green and orange lines highlight the entries relative to the examples shown in Fig. 3b, c and discussed in the main text. For a version without examples highlights and one without thresholds see Supplementary Fig. 13a, b.
