Far- and near-field photon noise limits to the detectivity of nanometer-thick thermal detectors
Olivier Merchiers, Aapo Varpula, Kirsi Tappura +2
Thermal-radiation detectors such as bolometers -- often found as thin, suspended films -- are intrinsically limited by their optical absorption properties and by their intrinsic th…

Infrared Bolometers Based on 40-nm-Thick Nano-Thermoelectric Silicon Membranes
Anton Murros, Kuura Sovanto, Jonna Tiira +3
State-of the-art infrared photodetectors operating in the mid- and long-wavelength infrared (MWIR and LWIR) are largely dominated by cryogenically cooled quantum sensors when the t…
