Figure 5. (A) Dependence of photovoltage and R_v on the laser power; (B) Plots of R_v and D as a function of incident wavelength; (C) The functional relationship between t₉₀ and optical power; (D) The relationship between the output voltage and current and power. The wavelength was 650 nm with a power of 100 mW; (E and F) Output voltage and stability test results after three months. The wavelength was 405 nm with a power of 100 mW. R_v: Responsivity.
