Dopant-Induced Manipulation of the Growth and Structural Metastability of Colloidal Indium Oxide Nanocrystals
Bibliographic record
Abstract
Doping semiconductor nanocrystals is crucial for enhancing and manipulating their functional properties, but the doping mechanism and the effects of dopants on the nanocrystal growth and structure are not well understood. We show that dopant adsorption to the surfaces of colloidal In 2 O 3 nanocrystals during incorporation inhibits the nanocrystal growth. This phenomenon induces a surface stress which gives rise to a reduction in atomic volume and leads to the formation of metastable corundum-type In 2 O 3 for nanocrystals smaller than 5 nm. The growth beyond the critical size lowers the potential energy barrier height and causes the nanocrystal phase transformation. Direct comparison between Cr 3+ and Mn 3+ dopants indicates that the nanocrystal structure directly determines the dopant incorporation limits and the dopant electronic structure, which can be predicted and controlled. These results enable a new approach to designing multifunctional nanostructures and understanding the early stages of crystal growth in the presence of impurities.

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.
