Growth and characterization of InAs on (100) InP ultrathin single quantum wells using tertiarybutylarsine and tertiarybutylphosphine
Bibliographic record
Abstract
Ultrathin InAs/InP single quantum wells were grown by low-pressure metalorganic vapor phase epitaxy using tertiarybutylphosphine and tertiarybutylarsine, with nominal thicknesses between 2 and 3 ML. Characterization of a large number of samples by high-resolution x-ray diffraction (HR-XRD) and photoluminescence (PL) indicates an average InAs thickness very close to the nominal one. Photoluminescence excitation and absorption spectra of selected samples contain excitonic resonances associated with electron-hole transitions in 2 or 3 ML of InAs buried in InP. Only one set of these resonances appears in a given sample, thereby corroborating HR-XRD and PL measurements. Thus, our measurements indicate an absence of significant As–P intermixing.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
