Density of states in hydrogenated and tritiated amorphous silicon thin films obtained using the constant photocurrent method
Bibliographic record
Abstract
The constant photocurrent method (CPM) was implemented to determine the density of states in amorphous silicon below the Fermi level. Hydrogenated (a-Si:H) and tritiated (a-Si:H:T) amorphous silicon thin films, grown using the DC saddle-field deposition system, where analyzed with CPM. Tritium incorporated in amorphous silicon samples increases the defect state density over time. The results showed an exponential valence band tail and a peak of doubly occupied dangling bonds (D- ) positioned 1.24 eV below the conduction band. The defects in a-Si:H:T were monitored in time showing an increase of defect concentration of about two orders of magnitude. This trend evolved following the theoretical decay of tritium. The a-Si:H samples featured a valence band tail and a peak of singly occupied dangling bonds (D0). A halogen lamp was used to age the samples inducing the Staebler-Wronski effect. Upon illumination the defect density increased by one order of magnitude before saturating.

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.
