ELECTROMAGNETIC RADIATION DETECTOR Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: electromagnetic radiation detector has backing with successively applied layer of correcting dielectric and sensitive element manufactured in the form of vertical p-n junction with contacts and dielectric layer and multilayer system of alternating layers of metal-dielectric placed above it. Medium length L of sensitive element, thickness f of correcting dielectric, thermal conductivity k₁ of dielectric and k₂ of backing satisfy condition 3k₁L/k₂l>1, thickness of layer of metal d₁ and dielectric d₂ in multilayer system satisfy relations 1 ≅ d₁/d₂≅ 2,1 ≅ d₂/d₀≅ 2 where and thickness D of multilayer system is found from condition D²χ₀/l²χ ≪ 1 where χ₀ is thermal diffusivity of correcting dielectric layer, χ is thermal diffusivity of dielectric in absorption coat. EFFECT: enhanced operational efficiency. 3 dwg
