Abstract

fetched live from OpenAlex

The onset time of photocrystallization (PC) as a function of temperature in a-Se films designed for avalanche photodetectors is explored using Raman scattering experiments. The PC onset time τon is compared to the time-constant τIPD for irreversible photodarkening (IPD) studied in earlier work. Both τon and τIPD exhibit activated thermal behavior mediated by an energy barrier EB∼0.7–0.95eV. We suggest that the formation kinetics of PC and IPD in a-Se are governed by the same energy surface and configuration changes, occurring via photoinduced defects during the primary stage of crystallization.

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.
