Light absorption in a resistive-gate GaAs charge-coupled device
Bibliographic record
Abstract
A 128 pixel uniphase resistive-gate GaAs charge-coupled device was fabricated at the TRI University Meson Facility to study its optical absorption properties under monochromatic illumination in the visible and infrared range. It was found that when the incident light energy exceeded that of the band gap, there was a progressive reduction in the charge collection efficiency. This was attributed to a carrier recombination effect at the cermet–GaAs interface. A simple recombination model was proposed to explain the observation. A comparison between theory and measurement suggested a match between the two would require a minority carrier lifetime on the order of nanoseconds and an interface recombination velocity in the neighborhood of 107−8 cm/s. Such a high recombination velocity suggested a surface state density as high as the density of the surface atoms. Extrinsic absorption measurement indicated the presence of additional carrier generation in the wavelength range between 1.3 and 2.0 μm.

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.
