Microwave-Assisted Hydrothermal Synthesis of BiFe<sub><i>x</i></sub>Cr<sub>1–<i>x</i></sub>O<sub>3</sub> Ferroelectric Thin Films
Bibliographic record
Abstract
We synthesize ferroelectric BiFe x Cr 1– x O 3 thin films by microwave-assisted hydrothermal synthesis on (111) oriented Nb-doped SrTiO 3 substrates. Bi(NO 3 ) 3, Fe(NO 3 ) 3, Cr(NO 3 ) 3, and KOH are used in the precursor solution, along with deionized water. Combination of Raman and X-ray photoelectron spectroscopies confirmed the incorporation of chromium into the rhombohedral structure of BiFeO 3 . The effect of deposition time on the surface morphology and the ferroelectric properties of the films are analyzed. This reveals that if the deposition goes on beyond completion of the reaction (10 min at 120 W), the ferroelectric properties of the film deteriorate due to stoichiometry changes. Through piezoresponse force microscopy, we show that Cr significantly deteriorates the film retention, which cannot be recovered by thermal annealing.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
