Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

The pristine compound 1 thin film forms an Al/compound 1/ITO Schottky barrier diode with enhanced conductivity, rectification ratio, mobility, and carrier concentration under illumination.

Caveat: Light intensity and spectral conditions are not specified in the main text.

2004 · Conclusions · Linked to 11 structured results

Application RelevanceSupport assessment: High

Compound 1 is classified by the authors as a wide-band-gap semiconductor based on a 3.28 eV optical band gap.

Caveat: Optical gap is from a Tauc plot; no uncertainty is reported.

2001 · Optical characterization · Fig. 2 · Linked to 2 structured results

Structure Property LinkSupport assessment: Medium

The authors attribute the material's electrical conductivity and photosensitivity partly to structural flexibility arising from S-S bond formation.

Caveat: The link is an author interpretation; no direct structure-property perturbation experiment is reported.

1998 · Abstract · Linked to 4 structured results

Synthesis MechanismSupport assessment: High

The monomeric 2-mba ligand dimerises in situ through S-S bond formation to generate the 2,2'-dsb linker, producing the zigzag 1D Cd(II) coordination polymer.

Caveat: Supported by SCXRD, IR peak assignments, and SI structural tables; the oxidation medium is described qualitatively without a separate oxidant.

Transport MechanismSupport assessment: Medium

Forward-bias transport is assigned to ohmic/thermionic behaviour at low bias and SCLC at higher bias.

Caveat: The paper does not tabulate fitted slopes from Fig. 6; mechanism assignment is based on the authors' qualitative region analysis.
