Fig. 4 — a Resistance of the VO₂/MoTe₂ heterostructure as a function of temperature (red, heating; blue, cooling). The inset shows the extracted ΔI_ds and ΔT, in which ΔI_ds increases with ΔT with slopes of γ₁ and γ₂. b Schematic of the bolometer mode for detecting MWIR to LWIR. c I_ds − V_ds curves for different incident laser wavelengths (black, dark; green, 10 μm, 41.6 μW; blue, 4.2 μm, 40.6 μW; red, 2.8 μm, 37.1 μW). The inset shows the calculated responsivity for the three wavelengths as a function of V_ds. d Temporal response of the photocurrent under laser illumination of 10 μm, 4.2 μm, and 2.8 μm. e Power dependence of the heterostructure. The responsivity rapidly increases when the laser power exceeds 157 μW, indicating the metal–insulator transformation. f Temporal response of the photocurrent under high-power laser illumination of 157 μW.
