This dataset contains information about the results of angle-resolved photoemission spectroscopy (ARPES) measurements of twisted bilayer graphene as well as theoretical modelling of this experiment. It accompanies a peer reviewed academic publication in which the experiment and theoretical model are described in more detail. 2020-07-17 University of Bath public RightsHolder University of Bath Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/M507982/1 Doctoral Training Partnership - University of Bath China Scholarship Council https://doi.org/10.13039/501100004543 University of Bath https://doi.org/10.13039/501100000835 International Research Funding Scheme Award University of Bath https://doi.org/10.13039/501100000835 IMI Undergraduate Research Experience Award cent_nan The ARPES measurements were performed at the Spectromicroscopy beamline at the Elettra synchrotron (Trieste, Italy). Before measurements, the samples were annealed at 350 °C for 30 minutes. The experiment was then performed at a base pressure of 10^-10 mbar in ultrahigh vacuum and at the temperature of 110 K. We used photons with energy of 74 eV and estimate our energy and angular resolution as 50 meV and 0.5°, respectively. For each sample, we determined the twist angle by measuring the distance between the nearest BZ corners of the two layers. The theoretical graphs and spectra were produced using equations given in the text of the manuscript. Experimental ARPES data was transferred to Matlab for further analysis and processing. Theoretical simulations were also performed using Matlab. All the enclosed data is saved in Matlab formats. en 1 10.15125/BATH-00864 https://doi.org/10.1038/s41467-020-17412-0 pub Elettra Synchrotron open
