Abstract:
A promising flexible X‐ray detector based on inorganic semiconductor PbI2 crystal is reported. The sliced crystals mechanically cleaved from an as‐grown PbI2 crystal act as the absorber directly converting the impinging X‐ray photons to electron hole pairs. Due to the ductile feature of the PbI2 crystal, the detector can be operated under a highly curved state with the strain on the top surface up to 1.03% and still maintaining effective detection performance. The stable photocurrent and fast response were obtained with the detector repeated bending to a strain of 1.03% for 100 cycles. This work presents an approach for developing efficient and cost‐effective PbI2‐based flexible X‐ray detector.
