Dataset of photoemission valence-band mapping and band reconstruction of 2H-WSe2

<p>Photoemission band mapping, band structure calculation, and reconstructed band dispersion of layered semiconductor 2<em>H</em>-WSe₂, a type of 2D transition metal dichalcogenide.</p> <p><strong>Provenance</strong>: The experimental data were measured using the SPECS METIS 1000&nbsp;3D&nbsp;detector with extreme UV pulses centered at 21.7 eV as the photoemission light source. The samples were commercially purchased and directly used in the experiment.</p> <p>The calculated data&nbsp;were converted and preprocessed from an existing record (http://dx.doi.org/10.17172/NOMAD/2020.03.28-1), which contains the band structure of 2<em>H</em>-WSe₂&nbsp;calculated using density functional theory (DFT)&nbsp;at the level of LDA, PBE, PBEsol, and HSE06 exchange-correlation functionals using FHI-aims&nbsp;(version 171221_1).</p> <p><strong>Content</strong>: The data contain binned and&nbsp;preprocessed photoemission data;&nbsp;Preprocessed DFT calculations used for initializing the band reconstruction; Postprocessed band reconstruction data (including 14 identifiable valence bands).</p> <p><strong>Usage</strong>: The dataset may be used for reproducing the results in (https://arxiv.org/abs/2005.10210), computational benchmarks or separately for other materials science applications. For reconstruction, see the&nbsp;source code and examples on GitHub (https://github.com/mpes-kit/fuller).</p>
