Dynamic X-ray imaging with screen-printed perovskite CMOS array.

ABSTRACT: High performance X-ray detector with ultra-high spatial and temporal resolution are crucial for biomedical imaging. This study reports a dynamic direct-conversion CMOS X-ray detector assembled with screen-printed CsPbBr₃, whose mobility-lifetime product is 5.2 × 10^-4 cm² V^-1 and X-ray sensitivity is 1.6 × 10⁴ µC Gy_air^-1 cm^-2. Samples larger than 5 cm[Formula: see text]10 cm can be rapidly imaged by scanning this detector at a speed of 300 frames per second along the vertical and horizontal directions. In comparison to traditional indirect-conversion CMOS X-ray detector, this perovskite CMOS detector offers high spatial resolution (5.0 lp mm^-1) X-ray radiographic imaging capability at low radi
