Figure 4

(a) Dark J-V curves of the MoS2/GaAs and MoS2/h-BN/GaAs heterojunctions. (b) J-V curves of the MoS2/GaAs and MoS2/h-BN/GaAs heterojunctions under AM1.5G illumination. (c) Linear fitting of dV/dLnI~I data for obtaining Rs of the devices. (d) Transient PL of the bare GaAs substrate, MoS2/GaAs and MoS2/h-BN/GaAs heterojunctions. (e) Fitting of the PL decay time constant in the fast decay range and (f) in the slow decay range.
