Photocurrent analysis of In–Ga–Zn–O (IGZO) film
Bibliographic record
Abstract
We investigated the electrical properties of the In–Ga–Zn–O (IGZO) film under light illumination. We measured the photoconductivity of a-IGZO thin film under light illumination with various intensities. We extracted the photoexcitation activation energy and dark relaxation activation energy through extended stretched exponential analysis. Dark relaxation characteristics, which are related to the recombination process, show longer time constant, τ, larger effective activation energy E ac , and lower stretching exponent, β, with wider activation energy bandwidth, Δ ac , than those corresponding to those of photoexcitation. These indicate that recombination takes place more slowly and through more deeply bound activation processes with the broader distribution of activation energies than those corresponding to photogeneration process. The wider distribution for the dark relaxation energy for the higher light intensity suggests that the metastable state distribution is related to the distribution of the oxygen vacancy state, V o . We also concluded that the usage of the right value of the attempt-to-escape frequency is important to estimate the exact value of E ac .

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.
