Face‑/Edge‑Shared 3D Perovskitoid Single Crystals with Suppressed Ion Migration for Stable X‑Ray Detector (IMAGE)
Caption
- 3D perovskitoid Pb2CuGly2X4 (Gly = -O2C-CH2-NH2; X = Cl, Br) single crystals (SCs) with face-/edge-shared inorganic skeleton and CuGly2 pillars delivered a high ion migration activation energy of 1.06 eV.
- The Pb2CuGly2Cl4 SC X-ray detector presented low dark current drift (1.20 × 10–9 nA mm−1 s−1 V−1 at 120 V mm−1) and high sensitivity (9250 μC Gy−1 cm−2).
- The Pb2CuGly2Cl4 film-based thin-film transistor array detector offered an X-ray imaging capability with spatial resolution of 2.2 lp mm−1.
