Dark current in multilayer stabilized amorphous selenium X‐ray photoconductors
Bibliographic record
Abstract
Abstract Commercially available flat panel, direct conversion, digital X‐ray image detectors use a photoconductive layer of stabilized amorphous selenium (a‐Se) sandwiched between two electrodes to convert incident X‐ray radiation into stored electrical charge. These detectors use thin n ‐like and p ‐like blocking layers to trap charge carriers injected from the contacts and thus reduce the dark current by limiting the rate of carrier injection. The effect of each of these blocking layers is determined by measuring the dark current in 200 μm thick mammographic detector‐like samples of a‐Se with three different structures: a single intrinsic layer and n‐i and i‐p double layers. Dark current is measured as a function of time over 20,000 s and as a function of applied electric field over the range of −10 V/μm to +10 V/μm. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
