Composite Bolometer Based on Bi sub 2 Sr sub 2 CaCu sub 2 O sub 8+x Single Crystals

The properties of a prototype bolometer operating at liquid nitrogen temperature based on a Bi sub 2 Sr sub 2 CaCu sub 2 O sub 8+x single crystal 15 mu m thick grown by the flux method are described. The use of thin single crystals having low thermal capacities was suggested by the request of decrea...

Zusammenfassung:The properties of a prototype bolometer operating at liquid nitrogen temperature based on a Bi sub 2 Sr sub 2 CaCu sub 2 O sub 8+x single crystal 15 mu m thick grown by the flux method are described. The use of thin single crystals having low thermal capacities was suggested by the request of decreasing the response time tau of the device. Preliminary results indicate that single-crystal-based far infrared bolometers can be competitive with the commercial detectors operating at room temperature.
