Abstract

A one-dimensional analytical thermal model applied to thin-film high-Tc superconductors provides a convenient technique for calculating the bolometric response of these films to modulated irradiation. Significant features of the model include modulated radiative heating of the film, film/substrate and substrate/cold finger thermal boundary resistances, and Joule heating within the film. The calculated voltage response is in qualitative agreement with measured data, and exhibits the same trends as the data for all calculated frequencies. In a parametric study, the effects of varying substrate/cold finger thermal boundary resistance and substrate thickness are shown to be especially significant with regard to the responsivity at low frequencies.
