A Type-II Bismuth Iodide Ferroelectric for Sensitive X-ray Detection and Single-Pixel Imaging.
Bismuth iodides have emerged as a promising class of novel semiconductors for direct X-ray detection due to their nontoxicity and strong X-ray absorption. However, translating the electrical response of Bi-based detectors into spatially resolved X-ray images remains challenging. Here, we report a one-dimensional (1D) h...
