Abstract
Electron transport in vacuum-deposited a-Se films with thicknesses varying from 13 to 501 μm has been investigated by conventional time-of-flight (TOF) and interrupted field TOF experiments. To separate the influences of electric field and the thickness, all TOF experiments were performed at a constant electric field. It has been found that the electron mobility is relatively constant in thick films (L > 50 μm) and increases in thinner films (L < 50 μm) with decreasing thickness. On the other hand, the electron lifetime is relatively thickness independent in films with thickness L > 50 μm, but drops sharply in thin films when L < 50 μm. These observations can be explained based on the density of states model that includes three types of traps forming Gaussian-like distributions within the mobility gap as reported in Koughia et al. (J. Appl. Phys. 97, 033706 (2005)).

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 it
