Abstract
Dual-gate transistors enable tunable electrical behavior by introducing a second gate electrode, offering enhanced control over channel formation and threshold voltage ( V th ). Here, we report a dual-gate-controlled ZnON thin-film transistor (DGC-TFT) capable of finely modulating V th (Δ V = 0.34 to 0.54 V) through independent top and bottom gate inputs. By characterizing the transfer and output curves under various bias combinations, we reveal systematic V th shifts and dual-channel switching behavior arising from asymmetric gate dielectrics, organic parylene (top) and SiO 2 (bottom). Finite-element TCAD simulations provide insights into the potential profiles, carrier distributions, and gate coupling mechanisms governing this behavior. Through this precise gate control, we demonstrate a dynamically tunable complementary inverter and implement five distinct logic functions (inverter, AND, OR, NAND, and NOR) using a single DGC-TFT device. These results highlight the promise of dual-gate architectures for compact, reconfigurable logic systems and adaptive circuit design.

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
