p-Type vdW Semiconductor CrSCl Featuring Multipolarity Coexistence
Bibliographic record
Abstract
Multipolar materials represent a paradigm shift in energy conversion, nonvolatile memory, and multifunctional sensing, enabling innovative, compact, and energy-efficient devices. However, achieving multipolarity in a single material is challenging due to often conflicting structural and electronic requirements. Herein, for the first time, we synthesized a p-type vdW semiconductor CrSCl featuring the coexistence of piezoelectricity and ferromagnetism. The carrier mobility of CrSCl at room temperature was found to be approximately 473.7 cm 2 v –1 s –1 . Few-layer CrSCl crystals exhibit stable intrinsic magnetic order and effective piezoelectric coefficients. Theoretical calculations confirm that the magnetic properties of the CrSCl stem from its (a 1 ) ↑ 1 (1e) ↑ 2 electron configuration and verify the stability of the ferromagnetic ground-state. The novel material CrSCl, a 2D ferromagnetic semiconductor with piezoelectric properties, enriches the class of transition-metal-based sulfide halides and provides a robust foundation for developing scalable 2D magnetic spintronics devices.

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.
