Solar-blind deep-ultraviolet (DUV) photoconductive detectors based on an LaAlO(3) (LAO) single crystal with interdigitated electrodes are reported. The LAO detectors show a high sensitivity to DUV light with wavelengths less than 210 nm, and the DUV/

A high-sensitive and fast-response photodetector based on BiFeO3 (BFO) ferroelectric thin film is fabricated using coplanar electrode configuration. A large photocurrent/dark current ratio is found up to two orders of magnitude at 1 V bias. Enhanced

The erasure of photoinduced resistance (PR) by the magnetic field was investigated in manganite films. The PR was significantly suppressed when a magnetic field was introduced at low temperature. The decrease (or increase) of PR with increment of mag

Epitaxial TiO2 thin films were fabricated on LaAlO3 single crystal substrates by RF magnetron sputtering. Ag electrodes were then evaporated on the TiO2 thin films to form metal–semiconductor–metal photoconductive detectors. The TiO2 photodetecto

We fabricate low-noise visible-blind ultraviolet photodetectors of indium tin oxide/SrTiO3/Ag (ITO/STO/Ag) based on the properties of STO bandgap excitation and the conductance of ITO thin film. The ITO films are epitaxially grown on STO wafers as el
