Probing the indium clustering in InGaAs∕GaAs quantum wells by room temperature contactless electroreflectance and photoluminescence spectroscopy
Bibliographic record
Abstract
Room temperature contactless electroreflectance (CER) supported by photoluminescence (PL) has been proposed as a fast and nondestructive ex situ technique for testing the effect of atom clustering in quantum wells (QWs). The indium clustering in InGaAs∕GaAs QWs was achieved by increasing the growth temperature. It has been shown that this effect causes significant changes in the spectral response. While the line shape of the GaAs-related CER feature remains unaffected there appear broad resonances similar to those for naturally inhomogeneous ensemble of self-assembled quantum dots instead of sharp and intensive lines characteristic for QWs. Additionally, the PL signal exhibits a quantum-dot-like behavior as well, i.e., strongly broadened Gaussian-like peaks with linear excitation power dependence on their intensity and the occurrence of the state filling effect for high excitation.

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.
