Abstract
The drain current-voltage (I-V) characteristics of Schottky-barrier carbon nanotube field-effect transistors (FETs) are computed via a self-consistent solution to the two-dimensional potential profile, the electron and hole charges in the nanotube, and the electron and hole currents. These out-of-equilibrium results are obtained by allowing splitting of both the electron and hole quasi-Fermi levels to occur at the source and drain contacts to the tube, respectively. The interesting phenomena of bipolar conduction in a FET, and of drain-induced barrier thinning (DIBT) are observed. These phenomena are shown to add a breakdown-like feature to the drain I-V characteristic. It is also shown that a more traditional, saturating-type characteristic can be obtained by workfunction engineering of the source and drain contacts.

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
