Theory of space-charge layer dynamics at oxide-semiconductor interfaces under optical modulation and detection by laser photocarrier radiometry
Bibliographic record
Abstract
The dynamic theory of the optically modulated space-charge layer (SCL) resulting from band bending at a Si–SiO2 interface was developed in terms of the density of interface charges occupying band-gap energy states. Expressions were derived for these interface charge densities, interacting with the free-carrier density wave generated in the SCL and in the quasineutral region (bulk) by an intensity-modulated super-band-gap laser. The residual and modulated interface charge coverage affects the band-edge-to-impurity state recombination and the concomitant near-infrared photon emission comprising the photocarrier radiometry (PCR) signal. The PCR theory incorporating these effects was further developed. It was found to involve the dc, fundamental, and entire harmonic spectrum of the excitation frequency as a result of the optical modulation of the curvature of the energy bands and the SCL width at the interface.

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.
