Interface layers in In0.532Ga0.468As/InP superlattices
Bibliographic record
Abstract
Polarized far infrared reflectance was measured at oblique incidence for InGaAs/InP superlattices grown lattice matched on InP(100) wafers by chemical beam epitaxy. The contributions to the reflectance spectrum of the phonon modes of the individual layers were resolved with a generalized analysis procedure. For very thin (0.25 nm thick) alloy layers we observed InAs-like, GaAs-like, InP-like, and GaP-like modes consistent with alternating interface layers composed of InAsP and InGaAsP and having a total thickness per period of 1.2 nm. Surprisingly, the InP spacer layers were found to be compressively strained, with the strain increasing with the layer distance from the substrate. This effect is a consequence of the uncompensated strain in the asymmetric structure of the interface layers.

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.
