Ultra-sensitive, self-powered, CMOS-compatible near-infrared photodetectors for...
Silva, Nuno E.; Jayakrishnan, Ampattu R.; Kaim, Adrian; Gwozdz, Katarzyna; Domingues, Leonardo; Kim, J. S.; Istrate, Marian C.; Ghica, CorneliuSelf-powered near-infrared (NIR) photodetectors are essential for surveillance systems, sensing in IoT electronics, facial recognition, health monitoring, optical communication networks, night vision, and biomedical imaging. However, silicon commercial detectors need external power to operate and cooling to suppress large dark currents. This work demonstrates a new class of CMOS-compatible self-powered NIR phot...
The ferro-pyro-phototronic effect for high-performance self-powered photodetectors
Jayakrishnan, Ampattu Ravikumar; Silva, José Pedro Basto; Gwozdz, Katarzyna; Gomes, M. J. M.; Hoye, Robert L.Z.; MacManus-Driscoll, Judith L.Self-powered photodetectors are advantageous over conventional photodetectors because they can have outstanding performance in the absence of an external power source, which is important for a range of applications, including in the Internet of Things. Current research has demonstrated different types of self-powered photodetectors utilizing the photovoltaic effect, pyroelectric effect, piezoelectric effect, an...
