Photothermal Radiometric Frequency-Swept Studies of Kinetics Process In P-Si Wafers
Bibliographic record
Abstract
Frequency-swept (chirped) infrared photothermal radiometry was combined with conventional single-frequency modulation of an Ar ion laser beam to yield a quantitative study of the surface-state annealing process induced by the low fluence laser beam on n and p-type Si wafers. The appearance of signal transient was found to be strongly dependent on the electronic quality of the wafer surface and was absent in the thermally oxidized p-si wafer. The low injection carrier minority lifetimes and diffusion coefficient were not affected by the laser-surface interaction, but the front surface recombination velocity strongly decreased with the time exposure, in the case of n-Si (positive transient). It was found that in the case of p-Si wafers with negative transient both carrier-lifetime and front surface recombination velocity exhibit changes. A two trap rate model was advanced to explain the positive transient behavior in terms of surface-state annealing and carrier injection.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
