Transport, Magnetic and Optical Properties of a Quasi-Two-Dimensional Organic Metal Based on BEDO-TTF (Bis-(Ethylenedioxy) Tetrathiafulvalene)
Bibliographic record
Abstract
Polarized reflectivity spectra, tight binding band structure calculations as well as magnetoresistance and magnetization measurements have been carried out for the new quasi-two-dimensional organic conductor β″-(BEDO-TTF)5[CsHg(SCN)4]2. Polarized reflectivity and optical conductivity spectra have shown that at low temperatures this salt exhibits metallic behaviour in the direction perpendicular to the BEDO-TTF stacks, but non-metallic behaviour in the direction parallel to the stacks. It is supposed that the non-metallic behaviour is due to the dimerization of BEDO-TTF molecules in the stacks at low temperatures. Tight binding calculations suggest that the Fermi surface can be described as containing two contributions: a closed two-dimensional portion associated with holes and a open, pseudo-one-dimensional portion associated with electrons. Shubnikov-de Haas and de Haas-van Alphen oscillations have shown that some frequencies of their complicated Furie spectra are in good agreement with the calculated Fermi surface. The other frequencies of the spectra can be well understood in the frame of the quantum interference effect.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
