Abstract
We have performed a detailed investigation of the fabrication and switching characteristics of ZnO-based memristive devices. The effects of doping and various metal contacts have been studied. It is observed that, with the use of Al metal contacts and ZnO:Al layers, relatively high ROFF/RON ratios of 200 can be achieved. Much improved device stability and reproducibility, on the other hand, can be realized by using either nominally undoped or Mg-doped ZnO memristive layers. The experimental results may be well explained by an oxygen vacancy formation and migration model. The present work represents an important step in realizing high performance ZnO-based memristive devices for future nonvolatile memory applications.

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
