a C1s spectra in x-ray photoelectron spectroscopy (XPS) splits upon hydrogenation, is indicative of intercalated graphene devoid of the buffer layer. b Transfer curves of monolayer epitaxial graphene (EG) and bi-layer quasi-freestanding epitaxial graphene (QFEG) shows the change in the position of the Dirac point before and after hydrogenation indicating the n-type doping and the p-type doping, respectively. c Band alignments of several semiconducting TMDs with conventional contact metals like titanium and gold, and n-type EG and p-type QFEG. These numbers have been extracted from literature and experimental values (adapted from ref. 10).
