An analysis for the broad-band absorption enhancement using plasmonic structures on uncooled infrared detector pixels
(SPIE, 2012-05)This paper introduces an analysis on the absorption enhancement in uncooled infrared pixels using resonant plasmon modes in metal structures, and it reports, for the first time in literature, broad-band absorption enhancement ... -
Analytic modeling of patterned high-Tc superconductive bolometers: film and substrate interface effects
(SPIE, 1998)Superconducting film and substrate interface effects on the response of superconductive edge-transition bolometers are modeled with a one dimensional thermal model in closed form, for samples with large area patterns ... -
Analytic thermal modeling for dc-to-midrange modulation frequency responses of thin-film high-Tc superconductive edge-transition bolometers
(Optical Society of America, 2001)Thin-film superconductive edge-transition bolometers are modeled with a one-dimensional analytic thermal model with joule heating, film and substrate materials, and the physical interface effects taken into consideration. ... -
Atomic-layer-deposited zinc oxide as tunable uncooled infrared microbolometer material
(Wiley-VCH Verlag, 2014)ZnO is an attractive material for both electrical and optical applications due to its wide bandgap of 3.37 eV and tunable electrical properties. Here, we investigate the application potential of atomic-layer-deposited ZnO ... -
Broadband absorption enhancement in an uncooled microbolometer infrared detector
(SPIE, 2014)This paper introduces a method for a broadband absorption enhancement in the LWIR range (8-12 μm), in single layer microbolometer pixels with 35 μm pitch. For the first time in the literature, this study introduces a very ... -
Digitally alloyed ZnO and TiO2 thin film thermistors by atomic layer deposition for uncooled microbolometer applications
