The crystal structure transforms from orthorhombic to tetragonal at 88 °C and then cubic 130 °C.
Abstract The detection of ionizing radiation such as X‐ray, γ‐ray, α‐particle, and neutrons has been widely required in medical industrial areas. Perovskite semiconductor detectors are arousing widespread interest achieving significant progresses this area. Unique material strengths, large attenuation coefficient, defect tolerant nature, balanced carrier mobilities, feasible preparation techniques, make perovskite detector a strong competitor to existing commercial products. Inspired by the...
Polycrystalline perovskite films offer promise for next-generation X-ray flat-panel detectors due to their ease of large-area fabrication. However, the perovskite–thin-film transistor (TFT) manufacturing mismatch causes defects (e.g., pores, fracture, and delamination), impacting device yield dead pixel rates. We identify that thermal stress between film TFT array plays a pivotal role in causing these defects. first propose strategy adding an anisotropic conductive adhesive as buffer layer...
Further improvement of optoelectronic performance is a target for all-inorganic lead halide perovskite material CsPbBr3; however, it greatly limited by the quality which dominated to some extent defects, especially intrinsic point defects. In this study, defects in melt-grown CsPbBr3 crystals were studied thermally stimulated current technology and simultaneous multiple peak analysis (SIMPA) method. The defect formation mechanism was analyzed systematically combining SIMPA fitting results...
Lubricated surfaces have recently been introduced and studied due to their potential benefit in various configurations applications. Combining the techniques of total internal reflection microscopy interference microscopy, we examine dynamics an underlying air film upon drop impact on a lubricated substrate where thin liquid is immiscible drop. In contrast solid even smallest asperities cause random breakup entraining film, report two failure mechanisms surfaces. particular, using ≈5 μm...
As a typical perovskite compound, cesium lead bromine (CsPbBr3) has been widely studied because of its different kinds optoelectronic applications. For high-energy ray detection, long-term stability CsPbBr3 single crystal detectors is affected by ionic transport when working under an applied bias. In this paper, the current-voltage hysteresis at temperatures was investigated. The so-called temperature-dependent transient response measurements were used to study characteristics crystal....
Inverted flexible perovskite solar cells (PSCs) typically employ expensive metals as the counter electrodes, which are brittle and corrodible by perovskite, leading to a sharp performance drop under continuous bending, air exposure, thermal stress, or light illumination eventually retard commercialization. Herein, low-cost Bi2Te3 electrode was employed using simple evaporation process. The resultant device achieved an excellent power conversion efficiency of 18.16%, among highest reported...
Abstract Scintillators play a crucial role in the fields of radiation detection and imaging, but it is formidable challenge to meet demands for large size, high light yield, fast response simultaneously.

However, their poor stability against moisture and oxygen significantly limits practical Developing hybrid with improved is essential yet remains a considerable challenge. Lead-free A3Bi2I9 have become attractive semiconductor materials next-generation X-ray sensing because of elevated bulk resistivity, efficient absorption, low ion migration. Nonetheless, the increased spacing between...

There are existing applications of underground sensing, such as soil monitoring for agriculture and air quality in coal mines. From a severely impaired channel to practical considerations power conservation. It is necessary reexamine terrestrial WSN communication protocols develop new which address these issues. We show that the condition highly dependent on properties or rock, particularly water content. present also major research challenges at each layer protocol stack cross-layer solution.
It is difficult to dope Al into main grains of ZnO varistor ceramics, especially for small doping amount. Generally, all raw materials including dopant are directly mixed together and sintered ceramics. However, in this direct process, apt stay grain boundaries, almost does not enter grains. This harm the electrical properties varistors. In paper, we proposed a two-step process. Al2O3 powder was first only with part pre-sintered. The pre-sintered other additives such as Bi2O3 rest ZnO. Then...
