Abstract
A thermal detector includes a transducer layer of semiconducting yttrium barium copper oxide which is sensitive at room temperature to radiation and provides detection of infrared radiation. In a gate-insulated transistor embodiment, a layer of ferroelectric semiconducting yttrium barium copper oxide forms a gate insulator layer and increases capacitance of the transistor or latches the transistor according to the polarization direction of the ferroelectric layer.
