Abstract

fetched live from OpenAlex

This paper investigates the reverse current-voltage (I-V) characteristics of inverted staggered hydrogenated amorphous silicon (a-Si:H) thin-film transistors (TFTs). Three mechanisms have been identified as the source of the reverse current: ohmic conduction, front channel conduction, and backchannel conduction. Ohmic conduction constitutes the physical limit for the reverse current and is due to the intrinsic conductivity of the a-Si:H and associated dielectric layers, which correlates with process integrity. The accumulation of holes and electrons at the front and back a-Si:H/a-SiN/sub x/:H interfaces, respectively, forms the basis of the other two leakage mechanisms. The relative dominance of the one or the other mechanism depends on bias conditions, TFT geometry, and process conditions. This paper identifies these sources of leakage current and examines the effect of the critical geometrical parameters (such as channel length and overlap length) and bias conditions on these leakage components. Physical models to predict bias and geometry dependences are presented for a quantitative analysis of the leakage current. Modeling results corroborate experimental observations of leakage current extracted from a large number of TFTs that are put in parallel for improved measurement accuracy. The physical parameters of the model provide a method for estimation of the significant interface and bulk properties of the structure.

Teacher imitation

Not 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.
