Abstract

fetched live from OpenAlex

The unusually low hole mobility observed in heavily p-type doped dilute GaSbxAs1−x alloys is explained in the context of the valence band anticrossing model. The anticrossing interaction between the localized p-states of the Sb atoms and the extended states of the GaAs host leads to a significant reconfiguration of the valence band structure and results in a greatly enhanced scattering of holes by state broadening effects in As-rich alloys. These results suggest that the mobility drop is fundamental in nature and indicate that the valence band anticrossing model is capable of describing the electronic transport properties of highly mismatched alloys.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
