Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
HITP-Ni-NS_240 min has lower orientation than 1 and 60 min samples, shown by an additional 001 reflection in the in-plane XRD profile.
12 (journal p. 780) · 3.1.7 Effect on crystal structure and orientation · Fig. 8f · Linked to 2 structured results
Planar conductance increases with longer standing time because larger crystalline domains, attached HITP-Ni_subphase and higher radical content improve carrier pathways.
Caveat: Conductance values are read from a plotted log-axis figure; conductivity was not tabulated and film thickness is heterogeneous.
14 (journal p. 782) · 3.3.2 Correlation between nanosheet characteristics and carrier conduction · Fig. 10; Fig. 11 · Linked to 5 structured results
Surface compression improves HITP-Ni-NS surface coverage and increases device conductance up to about 10 mN m-1.
Caveat: Conductance versus pressure values are graph-read estimates and only HITP-Ni-NS_60 min was tested for this pressure series.
12 (journal p. 780) · 3.3.1 Planar current-voltage characteristic · Fig. S35 · Linked to 3 structured results
Some HATP dissolves into the Ni2+ subphase to form HITP-Ni_subphase, which floats and attaches to HITP-Ni-NS, especially at longer standing times.
Caveat: The subphase attachment model is inferred from combined spectroscopy, AFM, XPS and visual observations rather than direct in-solution crystallisation kinetics.
11 (journal p. 779) · 3.2 Discussion on formation process · Fig. 9 · Linked to 4 structured results
Standing time after HATP spreading controls HITP-Ni-NS continuity, morphology, thickness, lateral size, crystallinity and orientation.
Caveat: Several morphology values are derived from imaging statistics and some figure-only trends lack tabulated uncertainties.
