Temperature dependent contactless electroreflectance study of intersubband transitions in a self-assembled InAs/InP (001) quantum dot structure
Bibliographic record
Abstract
Contactless electroreflectance, in the range of 18<T<300 K, has been used to investigate a self-assembled InAs/InP (001) quantum dot (QD) structure fabricated by metalorganic vapor phase epitaxy. Signals have been observed from all the relevant portions of the sample including the QDs, wetting layer, InP cap layer, and/or substrate. The energies of the QD transitions are in good agreement with an envelope function calculation based on the physical parameters of the QDs as observed from transmission electron microscopy and other relevant parameters. The temperature dependence of the energies of all transitions has been fit using both the semiempirical Varshni and Bose–Einstein-like expressions. It was found that extracted Varshni and Bose–Einstein fitting parameters are in the range of those for most III–V materials, both bulk and quantum well. However, the temperature variation for the energy transitions in the QDs is somewhat larger that reported for bulk InAs.

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.
