摘 要：Photodetection has attracted significant attention for information *** the implementation relies primarily on the photonic detectors,they are predominantly constrained by the intrinsic bandgap of active *** the other hand,photothermoelectric(PTE)detectors have garnered substantial research interest for their promising capabilities in broadband detection,owing to the self-driven photovoltages induced by the temperature *** get higher performances,it is crucial to localize light and heat energies for efficient ***,there is limited research on the energy conversion in PTE detectors at micro/nano *** this study,we have achieved a twoorder-of-magnitude enhancement in photovoltage responsivity in the self-rolled tubular tellurium(Te)photodetector with PTE *** illumination,the tubular device demonstrates a maximum photovoltage responsivity of 252.13 VW^(-1)and a large detectivity of 1.48×10^(11)*** disclose the mechanism of the PTE conversion in the tubular structure with the assistance of theoretical *** addition,the device exhibits excellent performances in wide-angle and polarization-dependent *** work presents an approach to remarkably improve the performance of photodetector by concentrating light and corresponding heat generated,and the proposed self-rolled devices thus hold remarkable promises for next-generation on-chip photodetection.
