In this study, electron beam lithography was used to implant electrostatic charges between electrodes to absorb DNA molecules. Nanoparticles and DNA were used as medium to adsorb perovskite (CsPbBr3) nanoparticles as crystal seed which then grew into a single crystal across the electrodes as a light sensor. Since the obstruction of the polycrystalline interface is avoided, the photo electron-hole pair generated when the single crystal perovskite is irradiated with light is directly transmitted to the electrodes, thereby efficiently performing high-efficiency light sensing.
