Broadband infrared thermal detection using manganese cobalt nickel oxide thin film
Abstract:
Room temperature, broadband infrared (IR) bolometer was investigated for the first time by using Mn1.56Co0.96Ni0.48O4 (MCNO) thin film with dielectric-metal-dielectric absorptive layers. The Si3N4/NiCr/SiO2 layer was constructed to improve light absorption. A responsivity of 98.6 V/W and D* of 2.1 × 107 cm∙Hz0.5/W@20 Hz, with a typical time constant of 14.5 ms, was obtained with a 1550 nm laser. The response spectra of the detector covered the range from near to far infrared, which greatly enhanced the potential of MCNO films in large-scale IR thermal detection applications. This study provides an efficient way to develop large scale, broadband MCNO IR detectors.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
