Abstract

Low-cost, high sensitivity and self-powered radiation detectors are highly demanded for photon flux detection. Here the fabrication of a self-powered X-ray detector with schottky structure is reported. Organic-inorganic perovskite CH₃NH₃PbBr₃ single crystals have been grown on ITO glass with the solution-processed method at relatively low temperature. Low work function Ag has been deposited on the surface of the crystal to form schottky contact. The devices exhibit an obvious response to both the wavelength of 405 nm laser and X-ray photons without external bias. The achieved X-ray sensitivity is up to 2.35 × 10⁻⁴ μC μGy⁻¹cm⁻² under 35 kV X-ray exposure without bias. The results demonstrated that this schottky diode based on perovskite enable for energy-saving X-ray detection.
