INFLUENCE OF ELECTRIC FIELD ON THE BINDING ENERGY OF HYDROGENIC IMPURITY WITH SPATIALLY DEPENDENT MASS IN NITRIDE PARABOLIC QUANTUM WELLS
Bibliographic record
Abstract
The ground state and binding energies of the hydrogenic impurity in a finite GaN/Al x Ga 1-x N parabolic quantum well (PQW) are investigated by using variational method. The effect of an electric field and spatial dependence effective mass (SDEM) are considered in the calculation. The results indicate that the effect of the SDEM on the energy levels is more obvious in the case of the narrower well width L. The effects decrease with increasing L, and tend to zero. The electric field shifts the energy levels towards lower energies with increasing well width L. Furthermore the ground state binding energy of the hydrogenic impurity in GaN/Al x Ga 1-x N PQWs is larger than that in GaAs/Al x Ga 1-x As PQWs. Therefore, we affirm that there is stronger quantum confinement effect in GaN/Al x Ga 1-x N PQW.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
