Overview

Fabricated photodetector exhibits high responsivity and detectivity in optoelectronics applications.

Key Points

  • The self-driven photodetector displays superior photosensing performance with responsivity of 992.9 mA W−1.
  • Detectivity of 6.77 × 10^9 Jones suggests exceptional capability for detecting light under visible wavelengths.
  • Fast switching times of approximately 140 ms and 110 ms highlight the efficiency of the snse/p-si heterojunction device.
  • The device's stable performance and high on-off ratios indicate strong potential for optoelectronic applications.
