| Popis: | A high-performance self-powered UV photodetector (UV-SPPD) using a PZT film was fabricated and characterized. It has a dual sensing mechanism that relies on the joint properties of a photoelectric effect and a triboelectric effect on the surface of the ferroelectric material. The UV-SPPD exhibits excellent responsivity (15 mA W−1), large detectivity (2×1010 cm Hz−1/2 W−1), a fast photo response time ( |
