Xj. Yi et al., HIGH-TC SUPERCONDUCTING LINEAR-ARRAY IR-DETECTORS USING YBA2CU3O7-DELTA THIN-FILMS, International journal of infrared and millimeter waves, 17(4), 1996, pp. 705-710
8-element linear array IR detectors based on high Tc superconducting f
ilms have been fabricated. The thin films were deposited by magnetron
sputtering on ZrO2 substrates and patterned by standard photolithograp
hic technique forming microbridge structure. An average detectivity of
1.85 X 10(9) cmHz(1/2)W(-1) with a variance of less than 20% in the d
etector-to-detector detectivity of the array has been obtained at the
operating temperature of 84 K. A bolometric response mechanism has bee
n discussed.
