Abstract: Methods and systems are provided for photodetectors employing a hybrid PIN or PN Lead Selenium (PbSe) junction. In some examples, the PbSe junction can include one or more semiconducting layers, including n-type layers, n+-type layers, p(i)-type layers, and/or p+-type layers, as a list of non-limiting examples. Photodetectors employing PbSe PIN or PN junctions are created. Also disclosed are methods for preparing photo-sensitive PbSe semiconducting layers for detection of electromagnetic energy (e.g., mid-wavelength infrared (MWIR)).
