Use of granular NbN as a superconducting bolometer

An ultrathin film of granular NbN is used as a superconducting bolometer. The bolometer has a high operating temperature (∼12 K), is very sensitive (∼5000 Ω/deg), and exhibits a fast thermal response time, which is estimated to be less than 10−10 sec.
