Study on the Theoretical Limitation of the Mid-Infrared PbSe N<sup>+</sup>-P Junction Detectors at High Operating Temperature Open
This paper provides a theoretical study and calculation of the specific detectivity-D* limit of photovoltaic (PV) mid-wave infrared (MWIR) PbSe n+-p junction detectors operating at both room temperature and TE-cooled temperature. For a typ…
