Schematic and equivalent electrical circuit illustration of p+-FLG/n–-ZnO NWs based heterojunction UV photodetector. The equivalent circuit diagram includes a photodiode (D) representing the p+-FLG/n–-ZnO NW heterojunction, series resistance (Rs), shunt resistance (Rsh), junction capacitance (Cj), and a light-dependent current source (Ilight) placed in parallel with the photodiode, modeling the electrical characteristics of the photodetector.
