Cavity-Backed Antenna-Coupled Nanothermocouples [PDF]
Scientific Reports, 2019 AbstractThis paper reports a two-orders-of-magnitude improvement in the sensitivity of antenna-coupled nanothermocouple (ACNTC) infrared detectors. The electrical signal generated by on-chip ACNTCs results from the temperature difference between a resonant antenna locally heated by infrared radiation and the substrate. A cavity etched under the antenna
