Mn and Sb-doped PbZrTiO 3 (PMSZT) ferroelectric thin films were integrated to high-T c superconducting YB2Cu3O 7-x (YBCO) thin films on LaAlO 3 (100) and YSZ/Si (100) substrates by the pulsed laser deposition technique. The PZT/YBCO and PM-SZT/YBCO infrared detectors were fabricated and examined as to their photovoltage and photocurrent in response to IR source temperature, and IR wavelength. The detector has relatively high IR sensitivity with a detectivity of ~ 108 cm · Hz 1/2/ W in the wavelength range of 3–16 μm.
