a Ti3C2Tx, b Mo2TiC2Tx, and c schematics of all the device configurations. d Band structure of SnS with Ag contacts, both when isolated and contacted. e Band structure of SnS and Ti3C2Tx, both when isolated and contacted. f Band structure of SnS and Mo2TiC2Tx, both when isolated and contacted. g, h Atom-projected density of states plots for Ti3C2F and Mo2TiC2O surface. The black dashed line shows the Fermi level in each case.
