Orthorhombic Non‐Perovskite CsPbI<sub>3</sub> Microwires for Stable High‐Resolution X‐Ray Detectors
Bibliographic record
Abstract
Abstract X‐ray detectors are used widely, but they suffer from short operational stability and insufficient absorptivity of X‐ray photons. Here, a strategy for room‐temperature, solution‐grown δ‐CsPbI3 monocrystalline microwires exhibiting one of the highest linear X‐ray absorption coefficients among known semiconductors is reported. In a metal–semiconductor–metal architecture, δ‐CsPbI3 demonstrates one of the lowest detectable X‐ray dose rates at 33.3 nGyair s−1, enabled by its exceptionally low dark current density of 12 pA mm−2. The detector remains stable following a continuous operation for a total accumulated dose of 1.44 × 106 Gyair, which is equivalent to 720 million chest X‐ray scans. The 1D crystalline nature of δ‐CsPbI3 enables a high X‐ray imaging resolution of 12.4 line pairs per millimeter (lp mm−1).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
