Energy localization in three-dimensional nanostructure
Chinese Academy of SciencesPhotothermoelectric (PTE) detectors have garnered substantial research interest for their promising capabilities in broadband self-driven photodetection. To get higher performances, it is crucial to localize light and heat energies for efficient conversion. Therefore, scientists in China fabricated a three-dimensional (3D) tubular detector by nanomembrane self-rolling, and remarkably enhanced performance has been achieved. The proposed self-rolled device holds promise for next-generation on-chip photodetection.
