Abstract

This paper reports optical and electrical performance study of high Tc superconductors, especially YBaCuO film. The behavior of high Tc superconductors at or near Tc was studied in detail. A high Tc superconducting transition-edge bolometer has been fabricated from YBaCuO thin film on a (100) SrTiO₃ substrate. The performance of the bolometer was studied. By using of the detectors, we also studied the photoresponse of YBaCuO film to He-Ne laser and far infrared laser. At or near the middle point of the film's transition temperature, the obtained voltage response signal of YBaCuO film to 1.5 mW He-Ne laser chopped at a frequency of 0.1 Hz is 10 mV. The relationship between the photoresponce signal to material, temperature and chopping frequency was studied in detail.
