Replication Data for: Thermal Transport in γ-InSe: Bulk Single Crystals and Thin Flakes

This dataset was created to document experimentally measured thermal and thermoelectric transport properties of layered metal chalcogenide thin films under controlled conditions. It includes temperature-dependent in-plane thermal conductivity, sample thickness, and supporting structural and compositional characterization data. The dataset enables analysis of phonon-mediated heat transport, validation of theoretical models, and comparison across samples with varying thicknesses and compositions. All data are curated with relevant metadata to support reproducibility and reuse by the research community.
