Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu-CAT@GP shows field-emission performance comparable to carbon-based cathodes, with low turn-on/threshold fields and high field enhancement factor.
Caveat: Comparison table is readable in the rendered SI surrogate; other comparator rows are literature values, not first-hand measurements in this paper.
4 / p004 · Results and discussion · Figure 4b; Table S2 · Linked to 5 structured results
High-conductivity graphite paper rapidly transports carriers to Cu-CAT emission tips, supporting excellent field-emission performance.
Caveat: The paper does not report a Cu-CAT cathode without graphite paper as a field-emission control; graphite-paper conductivity differs between main text and SI Table S3.
4 / p004 · Results and discussion · Linked to 5 structured results
Graphite paper is proposed to improve cathode stability by reducing thermal damage during high-current-density field emission.
Caveat: This is an attribution by the authors; no separate thermal-control experiment is reported in the main text.
4 / p004 · Results and discussion · Figure 5 · Linked to 4 structured results
Cu-CAT nanorods grown on graphite paper have similar crystal structure and crystallinity to reported Cu-CAT.
Caveat: Graphite paper peak intensity around 25.5-27.5 deg was too strong to display.
3 / p003 · Results and discussion · Figure 2c · Linked to 3 structured results
The 2D hexagonal Cu-CAT lattice and effective orbital overlap between Cu ions and HHTP ligands are proposed to give good charge-transfer characteristics.
Caveat: The statement is structural/electronic rationale rather than a direct transport mechanism proof in this paper.
