Abstract

fetched live from OpenAlex

<title>Abstract</title> Perylene-based columnar liquid crystal (LC) devices exhibit unipolar resistive switching (RS), clearly identified on cyclic J-V curve hysteresis, stable for several cycles. Trap-controlled SCLC conduction is responsible for the charge transport in the active layer, where the “set” and “reset” processes occur. The incorporation of ZnO@SiO2 quantum dots significantly enhances the RS response. The distinguishing result presented here is the ability to write-read-erase-read, controlling the "on" and "off" states by applying an external electric field, allowing to store and read information multiple times. An endurance of nearly one order of magnitude between the low and high RS states was determined over 50 consecutive cycles. The device proved to be resilient, preserving the resistive switching effect and memory capacity even after one year maintained at room temperature in ambient atmosphere. DFT calculations indicate a conduction mechanism based on reversible reductions of the perylene LC molecules. This article highlights the ability of LCs to store and process information via their resistivity, with potential for the production of low-cost and large-area nonvolatile printed organic memories.

Teacher imitation

Not 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.
