Oscillatory thermoelectric effect in quasi-two-dimensional organic conductors in a magnetic field
Bibliographic record
Abstract
A theoretical analysis is presented of the dependence of the thermoelectric power, when the temperature gradient is directed along the normal to the layers, in a layered conductor, with a quasi-two-dimensional electron energy spectrum on the magnitude and orientation of a strong magnetic field relative to the layers. The angular oscillations of the thermoelectric power, when the magnetic field is noticeably tilted from the normal to the layers result from the periodic dependence of the average electron velocity on the angle between the normal to the layers and the magnetic field. It is shown that, in a quantizing magnetic field at low temperatures, giant quantum oscillations of thermoelectric power as a function of both the magnetic field magnitude and the angle between the normal to the layers and the magnetic field occur. This quantum oscillation effect can be used with a high degree of accuracy as a good spectroscopic method for the experimental study of certain characteristics of a Fermi surface of quasi-two-dimensional organic conductors, such as the quasi-two-dimensionality parameter of the electron energy spectrum, cyclotron effective electron mass, and velocity distribution of charge carriers as well as an accurate determination of the extremal cross sections.

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.
