Hysteresis erasure in ZIF-8@ZnO nanorod array field-effect transistors through oxygen chemisorption-induced depolarization
Bibliographic record
Abstract
Zeolitic imidazolate framework-8 (ZIF-8) is a versatile candidate for next-generation electronics owing to its adjustable lattice and physicochemical properties. However, the utilization of ZIF-8 for the fabrication of solid-state electronics and circuit components, such as field-effect transistors (FETs), has not been realized thus far, primarily due to ongoing debates surrounding its electrical properties. In this work, we fabricated n-type FETs using ZIF-8@ZnO nanorod arrays. A significant hysteresis behavior was observed. It was demonstrated that this hysteresis cannot be assigned to the well-established ferroelectric effect but rather to the polarization of ZIF-8, wherein the electric field of the gate aligns the dipole of 2-methylimidazole through molecular orientation rotation. It was clarified that the process of annealing in air can result in the chemisorption of oxygen on methylimidazole, leading to a limitation in the rotation of methylimidazole. This restriction ultimately causes the depolarization of ZIF-8, resulting in the erasure of hysteresis. This study unfolds the tunable hysteresis behavior of ZIF-8 and its sensibility to oxygen, thereby highlighting the potential applications of ZIF-8 in FETs, nonvolatile memories, and gas sensors.

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.
