摘要：

We have used prethinned sapphire substrates to make a YBa2Cu3O7-x thin-film, transition-edge bolometer with peak detectivity of 6x10(9) cm Hz(1/2)/W near 4 Hz and 90 K. This is a new record for high T-c superconductor bolometers, and is comparable to the best detectivity yet achieved for a thermal-type infrared detector with no more than moderate cooling (liquid-nitrogen temperature and above). We discuss some simple improvements which may push the detectivity above 10(10).
