Perovskite/Silicon‐Nanowire‐Based Hybrid Heterojunctions for Fast and Broadband Photodetectors
Bibliographic record
Abstract
A hybrid photodetector fabricated with a halide perovskite and silicon nanowire (SiNW) heterojunction for broadband detection ranging from near‐ultraviolet to near‐infrared is reported. The device fabrication is conducted by directly coating chemically etched vertical SiNW arrays with perovskite thin films and nanofibers produced from liquid precursors. The optimized perovskite thin film/SiNW heterojunction‐based device under 532 nm illumination exhibits excellent spectral responsivity of 13 A W −1 , high specific detectivity reaching 10 13 Jones at 0.3 V external bias, and fast rise/fall times of 22.2/17.6 μs. The device shows very good stability under ambient conditions, even after 30 days of storage. Overall, this simple, all‐solution‐based hybrid photodetector offers great potential for the future integrated optoelectronic devices.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
