Abstract

fetched live from OpenAlex

A theoretical model for dc conductivity under high electric field in chalcogenide glasses is developed. This model, of correlated barrier hopping is used to treat both low field conductivity, which obeys Meyer-Neldel rule (MNR), and high field Poole-Frenkel (PF) effect. Both are incorporated in one model because the origin of electronic emission is the same: a deep well in which a polaron is trapped. We show that the characteristic temperatures associated with MNR and PF should be the same, as has been predicted using a rigorous adiabatic polaron hopping model, and previously demonstrated experimentally for fullerene films. We also predict that the extrapolated conductivity prefactors will be the same in the two cases. Experimental evidence from the literature suggests, but does not demonstrate conclusively, that the two predictions are satisfied for chalcogenide glasses. Finally, we interpret the result in terms of the multi-excitation entropy model for MNR.

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.
