Overview

Experimental study demonstrates a two-order-of-magnitude responsivity increase in self-rolled tellurium photodetectors, highlighting potential for on-chip photodetection.

Key Points

  • Photovoltage responsivity increases by two orders of magnitude in tubular tellurium devices through geometry-induced light and heat localization.
  • Under illumination, the tubular photodetector achieves a peak photovoltage responsivity of 252.13 V W−1 and detectivity of 1.48 × 1011 Jones.
  • Theoretical simulation confirms photothermoelectric conversion mechanisms, and the architecture supports wide-angle, polarization-dependent detection.
