Polarimetric Photodetectors
Due to the directional inversion of energy band, the photovoltaic detectors based on 2D anisotropic semimetal and ambipolar semiconductor exhibit an optoelectronic reverse phenomenon. In this image, the transport direction of photocurrent is readily reversed by tuning the gate voltage and incident light polarization, yielding a reversible rectifying and photovoltaic characteristic...
Polarimetric photodetector can acquire higher resolution and more surface information of imaging targets in complex environments due to the identification of light polarization. To date, the existing technologies yet sustain the poor polarization sensitivity (<10), far from market application requirement. Here, the photovoltaic detectors with polarization‐ and gate‐tunable optoelectronic reverse...
