Tailoring of Single-Crystalline Complex Ta<sub>5</sub>Si<sub>3</sub> Nanostructures: From Networked Nanowires to Nanosheets
Bibliographic record
Abstract
Single-crystalline Ta 5 Si 3 nanostructures with a complex morphology were synthesized through a catalyst-free, chemical vapor deposition method under low pressures. The morphology, structure, and composition of deposited nanostructures were studied by scanning electron microscopy, X-ray diffraction, and high-resolution transmission electron microscopy. These nanostructures have lengths of up to several tens of micrometers and an average thickness of 13 nm. It was found that the formation of networked Ta 5 Si 3 nanostructures is highly sensitive to the vapor pressure of tantalum chloride and silica and is based on a vapor–solid mechanism. Results indicate that, with the decrease of silica vapor pressure, the Ta 5 Si 3 networked nanowires evolve into networked nanoribbons and nanosheets via two-dimensional growth. Cyclic voltammetry measurements of the Ta 5 Si 3 nanostructures show superior electrochemical capacitance properties of nanosheets compared to nanowires. It is expected that these nanostructures have great potential applications for nanodevices in electronic and energy related applications.

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.
