Independent Control of Electron and Hole Localization in Core/Barrier/Shell Nanostructures
Bibliographic record
Abstract
By use of a two-band effective mass model and first-order perturbation theory, we demonstrate the capacity for complete spatial control over excitonic wave functions in core/barrier/shell nanostructures. By exploring parameter space with core size and barrier width as variables, we show that each exciton can be in a core-localized or shell-localized state (Type-I localization) and as well in a charge-separated state (Type-II localization). Furthermore, the width of each localization region in parameter space can be tuned by controlling material properties, providing design principles for nanostructures with desirable features for key applications. Depending on the localization regime of excitons, both radiative and nonradiative decay rates can be significantly enhanced or suppressed in these nanostructures, making them suitable for dual-color emission and for producing low threshold and broad bandwidth of optical gain.

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.
