Data are shown for (a, c) MoS2/Au and (b, d) WSe2/Au interfaces. Yellow-shaded bands (a, b) indicate the approximate n-type Schottky barrier heights (SBH) extracted from experiments, while blue-shaded bands (c, d) indicate the approximate extracted p-type SBH. Note that the entire box in (d) is shaded blue since explicit SBH values were not listed in the experiments. Experimental values have been extracted from refs. 10,12,13,14,15,25,26,27,28. Calculated QP (DFT) SBH values from this work are shown as filled (shaded) red (MoS2) and blue (WSe2) hexagons. “prist.” stands for “pristine”.
