Abstract
Perovskite single crystal X-ray radiation detector devices including an X-ray wavelength-responsive active layer including an organolead trihalide perovskite single crystal, a substrate layer comprising an oxide, and a binding layer disposed between the active layer and the substrate layer. The binding layer including a binding molecule having a first functional group that bonds to the organolead trihalide perovskite single crystal and a second functional group that bonds with the oxide. Inclusion of the binding layer advantageously reduces device noise while retaining signal intensity.
