I-V characteristics of the (a) MoS2, (b) TiS3, and (c) TiS3-MoS2 PDs under 532 nm laser illumination at different power intensities. Photocurrent versus incident power intensity for (d) MoS2, (e) TiS3, and (f) TiS3-MoS2 PDs under 532 nm laser illumination at an applied voltage of 10 V. Photoresponsivity versus incident power intensity for (g) MoS2, (h) TiS3, and i) TiS3-MoS2 PDs under 532 nm laser illumination at a supply voltage of 10 V.
