Abstract
Highly granular YBaCuO films on SrTiO3 substrates with Tc,o~90K and Jc > 104 A/cm2 were prepared by non-vacuum aerosol deposition. The optical response for these films was investigated on a 10 × 10 μm2 microbridge. Besides a bolometric response around the transition temperature, a sharp response peak was observed at low temperature and high bias current using a He-Ne laser (0.63 μm wavelength) illumination. This response was caused by a junction behaviour due to the presence of many boundary-type weak links in our microbridge.
