State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide

Advanced Photonics Research, EarlyView.
State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...

Composition dependence of giant electrocaloric effect in PbxSr1-xTiO3 ceramics for energy-related applications

Journal of Materiomics, 2019
PbxSr1-xTiO3 (x = 0.30, 0.35, 0.40, 0.45, 0.50 and 0.55) ceramics were fabricated by a solid-state reaction route. X–ray diffraction data at room temperature show PST samples shift from cubic to tetragonal phase with the increase of Pb2+ content.

Electrical Manipulation of Magnetic Domain Structure in van der Waals Ferromagnetic Fe3GaTe2 Using Ferroelectric PMN‐PT Single Crystal

Advanced Science, EarlyView.
2D van der Waals ferromagnets enable tunable magnetism for spintronics. This study demonstrates electric‐field‐induced control of Fe3GaTe2 magnetism on a PMN‐PT substrate, reducing coercive force and altering domain structures. The effects stem from interlayer gap modulation and enhanced DzyaloshinskiiMoriya interaction, establishing a path toward low ...
