IMPROVEMENT OF SPECTRAL CHARACTERISTICS OF HIGH-RESISTANCE THERMAL RADIATION DETECTORS,
Abstract
An improved method is proposed for the construction of high-resistance thermal-radiation detectors which use gold-black as the infrared absorber. Because of its poor adhesive properties, gold-black cannot be deposited directly on the sensitive material, but must be deposited on an interleafing layer, which causes high heat losses. Calculations are presented to demonstrate that these losses can be reduced to an insignificant amount if the interleafing layer is made of dielectric such as beryllium- or aluminum-oxides, which are good heat conductors, and if the layer's thickness is much less than the length of the incident heat wave.
