Abstract

YBa₂Cu₃O_6+x (YBCO) oxides are semiconductors (SC) at low oxygen content. IR detectors were processed with amorphous SC films, either planar or metal/YBCO/metal tri-layers. The response at 850 nm exhibited a low noise and fast pyroelectric behavior. THz detectors with planar antennas are considered.
