Tin−lead (Sn−Pb) mixed perovskites have emerged as promising candidates for near-infrared photodetection owing to their narrow bandgaps and outstanding optoelectronic properties. However, the facile oxidation of Sn2+ and the high defect density within the perovskite films severely limit the detection sensitivity and...
Metal halide CsCu2I3 (CCI) scintillators are promising candidates for X-ray detection due to their lead-free nature and large Stokes shift, which provides substantial spectral separation between excitation and emission and is favorable for reducing reabsorption. However, their practical applications are constrained b...
The thermal field distribution in the vertical gradient freeze (VGF) process strongly influences the formation of dislocations, residual thermal stress, and twins in germanium (Ge) single crystals, and its effective control is essential for reducing defect density. In this study, a full-scale three-dimensional unsteady...
