Gas‑Phase Construction of Compact Capping Layers for High‑Performance Halide Perovskite X‑Ray Detectors

Caption

  • A gas-phase method has been developed, which can directly grow two-dimensional perovskite on three-dimensional perovskite with nanoscale precision.
  • The steric hindrance of the organic layer within 2D perovskites influences the ion migration in lattice. Larger steric hindrance enables slower ion movement.
  • The constructed 2D/3D heterojunction device showed ultra-high sensitivity, ultra-fast response speed, and ultra-low dark current.
