Suppressed ion migration for high-performance X-ray detectors based on atmosphere-controlled EFG-grown perovskite CsPbBr3 single crystals

Halide perovskites have shown great potential for X-ray detection in medical imaging and product inspection applications. However, the ion migration in perovskites causes large noise and baseline drift, deteriorating the X-ray detection and imaging performance. Here we adopt the atmosphere-controlle...
