Aluminum Nitride Piezoelectric NEMS devices using 2-Dimensional Electrode Material

INV-13074 Background Traditional IR detectors based on semiconductor photon-detectors need cryogenic cooling, making them bulky, costly and inconvenient to use. Uncooled IR thermal detectors based on bolometric principle have been recently developed, which are much smaller, lighter, cheaper and power-efficient, making them good alternatives to semiconductor...
