Dark current and optical properties in asymmetric GaAs/AlGaAs staircase-like multiquantum well structure

CuInSe2 Quantum Dots Hybrid Hole Transfer Layer for Halide Perovskite Photodetectors

“…Figure e shows the ratio of photocurrent density to dark current density at different voltages by 100 mW cm –2 illumination. The minimum dark current density and the maximum ratio of the photocurrent density to the dark current density both occur at 0 V, indicating that the device has a feasible energy band structure, and the zero-offset voltage is avoided . We also summarized the functional relationship between the current and the power density, as displayed in Figure f.…”

“…The minimum dark current density and the maximum ratio of the photocurrent density to the dark current density both occur at 0 V, indicating that the device has a feasible energy band structure, and the zero-offset voltage is avoided. 27 We also summarized the functional relationship between the current and the power density, as displayed in Figure 3f. In general, the photocurrent density increases with the increment of the light density.…”
