Effect of Yttria-Stabilized Zirconia Thickness on Crystal Structure and Electric Property of Epitaxial CeO<sub>2</sub>/Yttria-Stabilized Zirconia Buffer Layer in Metal/Ferroelectric/Insulator/Semiconductor Structure
Bibliographic record
Abstract
The effect of yttria-stabilized zirconia (YSZ) film thickness on crystal structure and electric properties of epitaxial CeO2/YSZ films was investigated. The CeO2/YSZ films were prepared on Si(001) substrates by pulsed laser deposition (PLD). X-ray diffraction measurements and reflection high energy electron diffraction (RHEED) observation indicated that heteroepitaxial growths of CeO2 and YSZ were achieved with a cube-on-cube relation (CeO2[100] ∥YSZ[100] ∥Si[100]) regardless of the YSZ film thickness. Measurement of C–V characteristics showed ion drift; this ion drift decreased with the decrease of YSZ film thickness. Measurement of I–V characteristics indicated that the leakage-current for all films was low enough for the insulating layer in the metal/ferroelectric/insulator/semiconductor (MFIS) structure, however for the films with a thicker YSZ layer, a difference in current was observed at various measurement positions. The reason for this was ascribed to the differences in the microstructure.

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.
