Abstrakt: Examines the crossover between electron-phonon relaxation and diffusion transport of hot electrons in an niobium carbide microbolometer. Effect of high diffusivity on mixer device matching; Implication of the intrinsic noise mechanisms for mixer noise temperature; Disadvantage of using pure metals in the bolometer radio frequency impedance.
