Abstract
Abstract
The ZnO/Mg0.2Zn0.8O/Au flexible ultraviolet photodetector (UV PD) with a polyethylene terephthalate (PET) substrate was successfully prepared at room temperature, which is compared with Mg0.2Zn0.8O/Au without a ZnO buffer layer. ZnO/Mg0.2Zn0.8O/Au double-layer film is biased at low operating voltage, the spectral responsivity is improved by 2.77 times. This result provides a way to grow a buffer layer on PET to improve the responsieness of the device. After 0/50/100/200 bending times and storage for more than 90 days, the pet substrate maintains excellent mechanical stability and repeatability, which is suitable for practical applications.
