Infrared polarization-sensitive photodetectors are attractive owing to their widespread applications. Here, the authors report a long-wave infrared photodetector with an ultrahigh polarization sensitivity by leveraging the 1D geometry of Tellurium nanoribbon and the finite-size effect of a perfect plasmonic ...
Layered narrow bandgap quasi-two-dimensional (2D) transition metal dichalcogenides (TMDs) demonstrated excellent performance in long-wave infrared (LWIR) detection. However, pe low light on/off ratio and specific detectivity (D) due to pe high dark current of pe device fabricated using a single ...
Long-wave infraredCascadeUp-converterStep-bound-to-minibandReducing the dark current in an infrared (IR) photodetector is one of the most important aspects in improving the detector's performance. This article attempts to clarify the dominant paths of dark current and reduce it in a long-wave ...
