Surface-Dependent Phonon Dynamics in 9-Armchair Graphene Nanoribbon Arrays – Research Data

This dataset contains the experimental, processed, and derived data underlying the paper Surface-Dependent Phonon Dynamics in 9-Armchair Graphene Nanoribbon Arrays. The study examines the temperature-dependent Raman response of five 9-armchair graphene nanoribbon (9-AGNR) configurations differing in substrate, alignment, and coverage. The deposited data include the Raman measurements used in the analysis, processed spectra, accepted Raman peak parameters and uncertainties, temperature-dependent model outputs, thermal-expansion data used in the thermomechanical analysis, and numerical source data for the main-text and Supplementary Information figures and tables. Metadata describing the sample configurations, acquisition conditions, spectrum selection, fitting selection, and analysis parameters are also provided. The five configurations are: (I) aligned Au, low coverage; (II) aligned Au, high coverage; (III) unaligned Au, high coverage; (IV) unaligned Raman-optimised substrate, high coverage; and (V) aligned Raman-optimised substrate, high coverage. Analysis software associated with this dataset is maintained separately in the linked GitHub repository and paper-specific release.
