Abstract

Abstract Microbridges of thin films of YBa 2Cu 3O 7 were used to make infrared bolometers. Using a chopped cw-CO 2 laser at 10.6 μm, the peak responsivity of these films was measured as 0.5 V/W at a temperature of 90.3 K. The present experimental data agree well with a bolometric response of the irradiated films and calculations are presented to support this conclusion.
