High-performance n-channel 13.56MHz plasma-enhanced chemical vapor deposition nanocrystalline silicon thin-film transistors
Bibliographic record
Abstract
Hydrogenated nanocrystalline silicon (nc-Si:H) films were directly deposited by using 13.56MHz plasma-enhanced chemical vapor deposition at a substrate temperature of 260°C with highly hydrogen (H2) diluted silane (SiH4) gases. The nc-Si:H film showed a high Raman crystalline volume fraction (XC∼85%) and low oxygen concentration (CO∼1.5×1017at.∕cm3). The formation of high-quality nc-Si:H is explained in terms of the effective roles of atomic hydrogen in the plasma. Top-gate staggered n-channel thin-film transistors (TFTs) adopting 90–100nm nc-Si:H channel and ∼300nm hydrogenated amorphous silicon oxide (a-SiOx) gate dielectric layers showed a field-effect mobility (μFE) of ∼150cm2∕Vs, a threshold voltage (VT) of ∼2V, a subthreshold slope (S) of ∼0.23V∕dec, and an on/off current ratio of more than 106. The TFT performance reported here offers promise for the total integration of peripheral electronics for active-matrix flat panel systems.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
