摘要：
We have investigated the optical response of YBa2Cu3O7-delta grain boundary junctions as well as single crystal strip lines. For both devices, bolometric signal was detected between T(c)(zero) and T(c)(onset), whereas nonbolometric signal was observed only in a temperature range just above T(c)(zero) where the current-voltage characteristic showed nonlinear behavior. The content of nonbolometric signal in the total response signal was remarkably increased with decreasing the film thickness. The effect of a single grain boundary on the nonbolometric response was described.
