Energy band structure tailoring of InGaAsP/InGaAsP quantum well prepared by organometallic vapor phase epitaxy and measured by photoluminescence
Bibliographic record
Abstract
We report the theoretical and experimental results of the In/sub x/Ga/sub 1-x/As/sub y/P/sub 1-y//In/sub z/Ga/sub 1-z/As quantum wells (QW). Wafers prepared by low-pressure organometallic vapor phase epitaxy (OMVPE) were studied. The band offset ratios at the heterointerface and material's energy bandgap are determined from the model-solid theory of Van de Walle, while single partical model is used to solve the Schrodinger equation to predict the corresponding wavelength. For unstrained In/sub x/Ga/sub 1-x/As/sub y/P/sub 1-y//In/sub 0.53/Ga/sub 0.47/As quantum wells, the conduction band offset of bandgap difference (dEc%) can be formulated as: (dEc %)unstrained = 42.6 % - (25.4y) %; on the other hand, for strained In/sub x/Ga/sub 1-x/As/sub y/P/sub 1-y//In/sub z/Ga/sub 1-z/As quantum wells, the strain (S) changes the dEc% as: (dEc%)strain=(dEc%)unstrained + 1.3xS. Results of our samples, measured by photoluminescence and transmission electron microscopy measurements, demonstrate good agreements in devised unstrained QW structure with theoretical calculations.

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.
