Abstract

fetched live from OpenAlex

Band-edge optical properties of highly strained In(Ga)As/InGaAs quantum wells on InP with the bandgap wavelength longer than 2 mum are analyzed by using 6- and 8-band <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> middot <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</i> theory. It is demonstrated that the 8-band model is indispensable for the analysis of highly strained In(Ga)As/InGaAs quantum wells due to the strong coupling between conduction and valence bands induced by large strain in the well. Furthermore, an energy correction originating from the interaction between the spin-orbit coupling and the strain, which has been discarded in conventional <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">kmiddotp</i> theory, is taken into account, and the role of the effect for highly strained quantum wells is discussed. The photoluminescence peak wavelength and absorption spectra of In(Ga)As/InGaAs quantum wells calculated by 8-band model are in excellent agreement with those obtained by experiment, showing the validity of the results presented here.

Teacher imitation

Not 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.
