A COMPARISON OF THE NON-BOLOMETRIC MICROWAVE RESPONSE WITH THE BOLOMETRIC OPTICAL-RESPONSE OF TL-OXIDE AND BI-OXIDE SUPERCONDUCTORS

The distinction between the bolometric and non-bolometric responses of high Tc Ti- and Bi- oxide superconducting thin films is presented by comparison of the characteristics of the responses at different temperatures and chopping frequencies.

Description
Summary:The distinction between the bolometric and non-bolometric responses of high Tc Ti- and Bi- oxide superconducting thin films is presented by comparison of the characteristics of the responses at different temperatures and chopping frequencies. The bolometric optical response of the films is proportional to the dR/dT of the films; experimentally the peak optical response decreases as the chopping frequency of the radiation is increased. The nonbolometric response is not proportional to the dR/dT to the films and the peak microwave response was found to be almost independent of the chopping frequency.
