Hybrid ZnO Core–a-Si:H Shell Infrared Photodetectors Integrated With Thin-Film Transistors
Bibliographic record
Abstract
A novel lateral infrared photodetector was demonstrated using 3-D structures comprising of zinc-oxide nanowire (NW) cores and hydrogenated amorphous silicon (a-Si:H) thin-film shell. The 3-D infrared photodetectors showed a low dark current of ~10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-11</sup> - 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-12</sup> A and ~10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> - 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> light-on/light-off ratio with both constant and pulsed 1.55-μm wavelength light. A vertically integrated infrared sensor/thin-film transistor (TFT) device incorporating the 3-D infrared photodetector on the back channel of an a-Si:H TFT was fabricated, creating an integrated optical detector and a switch. The detector dark current was found to scale with the NW geometry on the TFT back channel and may be used to optimize the performance of the hybrid sensor-switch device.

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.
