Abstract

fetched live from OpenAlex

An innovative strategy is introduced, integrating metal–organic frameworks (MOFs) and bare carbon nanofibers (CNFs) within a nanocomposite, to address the challenges related to the broad absorption spectrum of traditional photodetectors. This advancement aims to eliminate the need for additional filters or intricate surface patterning in traditional photodetectors to achieve spectral selectivity, which is associated with high costs, and to facilitate enhanced spectral selectivity in the visible range, thereby paving the way for their widespread commercial adoption. By strategically leveraging the inherent strengths of both MOFs and CNFs while addressing their individual limitations, our method not only resolves challenges related to 3D MOFs and CNFs in spectrally selective photodetection but also significantly enhances optoelectronic properties. The resulting nanocomposite exhibits spectrally selective detection of violet light in the visible range, achieving a significantly enhanced responsivity of 27 A/W, detectivity of 1.66 × 10 11 Jones, and high external quantum efficiency of 8215% at a low optical power intensity of 27 μW/cm 2 at room temperature. This approach holds significant promise to advance photodetection technology in various applications requiring high-performance and spectrally selective detectors.

Full frame distilled prediction

Teacher imitation

Not 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.
