Resonant interlayer coupling in NbSe2-graphite epitaxial moiré superlattices (dataset)

The data are experimental angle-resolved photoemission spectroscopy (ARPES) data, reflection high-energy electron diffraction (RHEED)data, atomic-force microscopy (AFM) data and theoretical calculation data.

The ARPES data encode photoemission intensity as a function of energy and momentum, measured at I05-nano beamline, Diamond Light Source, and were saved in NeXus format. This can be readily loaded using standard Python packages such as h5py or the open-source peaks package. The RHEED data are in IMG format and can be opened using standard Python packages. The AFM data are in TIFF format and can be opened using standard graphics software and processed using the free Gwyddion software. Two Jupyter notebooks are included for reproducing the figures in the main text and supplementary information starting from the raw data files. These can be run using only open-source freely-available python libraries.

The theoretical calculation data consists of spectral function evaluated on a two-dimensional momentum mesh over a range of energies, provided in plain-text format that can be opened using any text editor. Each file follows the same structure. The first row lists the total number of momentum points, the total number of energy points, and the bounds of the energy range. Subsequent rows contain a momentum value in fractional coordinates, followed by the corresponding spectral function values for all energies.
