Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Electrochemical deposition is a versatile route to grow Cu3(HHTP)2 thin films on FTO and Au/SiO2 substrates while preserving the framework diffraction signature.
Caveat: FTO films adhered strongly and could not be effectively transferred for electrical measurement.
16 · Conclusions · Figures 4 and 7 · Linked to 3 structured results
No in-plane thermal conductivity was determined for Cu3(HHTP)2 films or pellets because sample roughness made accurate measurement difficult.
Caveat: This blocks first-hand ZT extraction for Cu3(HHTP)2 in this paper.
15 · Thermoelectric measurements of electrodeposited Cu3(HHTP)2 films · Linked to 1 structured result
Higher anodic potentials in the FTO series reduce domain size and appear to increase stacking-axis disorder, likely through faster oxidation and insufficient ligand coordination time.
Caveat: Crystallinity decrease is phrased by authors as appearing to decrease, not quantified by a full refinement.
10 · Anodic Electrosynthesis of Cu3(HHTP)2 onto Transparent Conducting Substrates · Figure 4; Table S3 · Linked to 5 structured results
The larger power factor in the electrodeposited film relative to the pellet is attributed to the interdependence of carrier density and Seebeck coefficient and may be tuned by film nanostructuring.
Caveat: Thermal conductivity was not measured and PMMA residue may influence conductivity.
16 · Thermoelectric measurements of electrodeposited Cu3(HHTP)2 films · Table S4 · Linked to 4 structured results
PMMA-assisted wet transfer removes the conducting substrate contribution without compromising Cu3(HHTP)2 crystallinity.
Caveat: Authors suggest PMMA residues may slightly lower film conductivity.
16 · Conclusions · Figures 6 and 7 · Linked to 3 structured results
Negative Seebeck coefficients in Cu3(HHTP)2 pellet and film indicate electron-majority transport and n-type semiconducting behaviour.
Caveat: Authors note earlier literature identified Cu3(HHTP)2 as p-type; they suggest solvent or gas adsorption may explain differences and more experimentation is needed.
7 · Thermoelectric measurements of Cu3(HHTP)2 pressed pellets · Figures 3 and 9 · Linked to 2 structured results
Cu3(HHTP)2 pellet and film show semiconducting behaviour because electrical conductivity increases with temperature.
Caveat: Conductivity-temperature values other than the 301 K points are presented graphically with error bars rather than tabulated in the main text.
