Abstract

fetched live from OpenAlex

Intervalence band absorption spectra of InP and related materials over a range of temperatures are calculated using different k⋅p methods for band structure. It is shown that band structure models which neglect valence band intermixing effects, such as the Kane model, fail to provide any quantitative agreement with experiment. However, the Luttinger–Kohn model [Phys. Rev. 97, 869 (1955)] if properly fitted, does yield quantitatively accurate results for InP, GaAs, and InGaAs, in wide spectral and temperature ranges of interest for practical optoelectronic devices without adjusting the effective masses and split-off energy.

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.
