Role of substrate in the pseudomorphic stabilization of rocksalt-type AlN phase in AlN/TiN superlattices
Bibliographic record
Abstract
The nonequilibrium B1 (rocksalt-type) AlN phase was successfully stabilized in stress-free AlN/TiN superlattices prepared by room-temperature pulsed laser deposition on thin film amorphous carbon substrates. The coatings displayed the same properties as reported for multilayers grown on thick crystalline substrates; namely, the existence of a critical thickness of AlN (about 1 nm for the present study) below which AlN crystallizes in the B1–AlN phase. Exceeding this value lead to AlN crystallization in its equilibrium hexagonal wurtzite-type structure, accompanied by considerable degradation of coating crystallinity due to the loss of coherent epitaxial growth of alternating TiN and AlN layers in the coating. It is concluded that neither an orientational effect of the substrate nor its stress-sustaining ability is required to provide a pseudomorphic stabilization of the nonequilibrium B1–AlN phase in AlN/TiN multilayered coatings.

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.
