Fig. 4: Layer-dependent electronic properties of V-doped WSe2.
From: Layer-dependent Schottky contact at van der Waals interfaces: V-doped WSe2 on graphene
a, b STS recorded for 1–3 ML of V-doped WSe2 (a) and of V dopants (b) in the topmost WSe2 layer (blue). The gray lines display the 1 ML data for comparison. The black arrows indicate the positions of the valence and conduction band edges for V-doped WSe2 and of the localized dopant state and the conduction band edge for V dopants. c, d Layer-dependence of conduction and valence band edge (c) and band gap (d) for undoped WSe2 (red), V-doped WSe2 (light blue), and V dopants (dark blue), respectively.
