Abstract
Present report deals with the optical tuning of electrical properties of PZT thin film based photodetector (PD). Lead Zirconium Titanate (PZT) thin film has been fabricated over epitaxially matched Strontium Titanate (STO) substrate using Pulsed Laser Deposition technique. Fine aluminium inter digital electrodes were patterned over PZT film to study the response of the PD. The photo response has been investigated by tuning the optical properties of the incident laser beam. The response was found to be modified according to the incident laser intensity and the distance between sample and laser. Moreover, PZT based photo detector was found to be highly sensitive towards small variation in the optical properties of the incident light. The intrinsic properties of the PZT thin film including its ferroelectric properties make it a novel material for the fabrication of UV based photo detector. The response of the PZT based Photodetector was found to be about 152 at a distance of 10cm between the PD and the UV laser of wavelength 365nm. The response time and recovery time were found to be 60 msec each which are much faster for UV detection as compared to other photodetectors. Moreover, a stable response was also observed on the repetitive UV sensing for the fabricated PZT based Photodetector.
