Self-powered X-ray detectors enable operating without applying bias, enabling detector portability and making them highly valuable in the industrial medical fields. This study demonstrates high-performance self-powered using polar α-BaTeMo2O9 (α-BTM) β-BaTeMo2O9 (β-BTM) oxide crystals. It is proven that carriers are driven by internal electrostatic field along axis, has a favorable effect on crystal detector. The β-BTM sensitivity of 300.2 µCGyair -1cm-2 under 40 keV X-rays, which 15 times α-Se (20 -1cm-2). structure simultaneously addresses inherent trade-off between dark current photocurrent enhancement observed conventional detectors. polarization α-BTM crystals leads to macroscopic resulting fields 34 66 V mm-1. Furthermore, ion activation energies BTM larger than 828 meV, higher most perovskite materials, excellent stability low current. breakthrough performance stems from synergistic effects built-in robust crystalline structure, opening new avenues for portable radiation detection technologies.

Abstract The realization of large‐area high‐quality perovskite thick films under an atmospheric environment without humidity control is confronting urgent challenge for the applications in X‐ray detection and imaging. A spray‐coating method with air as gas carrier employed to achieve flat‐panel applications. To further improve quality films, 10 µm‐thick CsPbIBr 2 (100)‐preferred orientation, low trap density (7.1 × 12 cm −3 ) high resistivity corresponding dark current (3.2 −9 A) are prepared via dual‐additive‐assisted (NH 4 SCN L‐α‐phosphatidylcholine (LP)) solution strategy relative 60% (60% RH). Thus, metal‐semiconductor‐metal‐structured (Au/CsPbIBr /Au) transverse device 40 KeV irradiation possesses a sensitivity up 1420 µC Gy −1 −2 weak electric field 18 V mm dose rate 3.3 µGy s that lower than ≈5.5 required routine medical diagnosis. Strikingly, unencapsulated maintains 80% (1120 original after 1000 h 45–55% RH. These results pave way practical

Due to their exceptional responses X-ray exposure, lead halide perovskites are recognized as ideal candidates for high-spatial-resolution detectors. However, an effective method deposit a large-area, submillimeter-thick, dense perovskite film detection has been lacking. In this study, strategy that combines saturated-solution-induced epitaxial growth with large-area blade-coating process developed produce large-size, submillimeter-thick CH3NH3PbBr3 films. The successive deposition of saturated precursor does not dissolve the underlying film. Instead, it promotes crystal by controlling rate over nucleation rate. obtained films exhibit columnar grain structure fewer pinholes and negligible residual lattice strain. As result, under source working voltage 40 kV, thick achieves sensitivity up 1938 μC Gyair–1 cm–2 −3 V bias, reduced dark current drift 1.78 × 10–4 nA s–1 V–1, limit 47 nGyair −2 bias; all above among best performances reported CH3NH3PbBr3-based Using point-to-point scanning method, clear image could be obtained. This study presents approach producing thick, dense, crack-free directly on substrates future applications.
