Fig. 6: Nonlinear photoconductivities under Fermi level tuning.
From: Colossal switchable photocurrents in topological Janus transition metal dichalcogenides
a The CC and SC conductivities of MoSTe as a function of the Fermi level EF. EF = 0 denotes that the Fermi level is at the valence band maximum. b An illustration that explains the sharp jump in the photoconductivity when EF is slightly inside the valence band or the conduction band.
