Abstract

fetched live from OpenAlex

Abstract The dilute bismide semiconductor GaAs 1–x Bi x is an interesting new semiconductor alloy with novel properties and potential device applications. Like the dilute nitride alloy GaAs 1–x N x , the dilute bismide shows a giant bandgap bowing effect. Bi alloying primarily affects the states in the vicinity of the top of the valence band rather than the bottom of the conduction band as in the case of N alloying. MBE growth of dilute bismides requires low growth temperatures (320‐390 °C) and near stochiometric group III/V ratios, due to the strong tendency of Bi to surface segregate under usual GaAs growth conditions. Optimal growth conditions are close to conditions that produce Bi and/or Ga droplets. In‐situ light scattering is found to be a useful tool for defining growth conditions that do not produce droplets on the surface. (© 2007 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)

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.
