Data for: Superconductivity in twisted double bilayer graphene stabilized by WSe₂
<p>Identifying the essential components of superconductivity in graphene-based systems remains a critical problem in 2D materials research, connecting this field to the mysteries that underpin investigations of unconventional superconductivity throughout condensed-matter physics. Superconductivity has been previously observed in magic-angle twisted stacks of monolayer graphene but conspicuously not in twisted stacks of bilayer graphene, although both systems host topological flat bands and symmetry-broken states. Here, we report the discovery of superconductivity in twisted double bilayer graphene (TDBG) in proximity to WSe<sub>2</sub>. Samples with twist angles 1.24 and 1.37 degrees superconduct in small pockets of the gate-tuned phase diagram within the valence and conduction band, respectively. Superconductivity emerges from unpolarized phases near van Hove singularities and next to regions with broken isospin symmetry, showing the correlation between a high density of states and the emergence of superconductivity in TDBG while revealing a possible role for isospin fluctuations in the pairing.</p>

Relaxation effects in twisted bilayer molybdenum disulfide
<p>Manipulating the interlayer twist angle is a powerful tool to tailor the properties of layered two-dimensional crystals. The twist angle has a determinant impact on these systems' atomistic structure and electronic properties. This includes the corrugation of individual layers, formation of stacking domains and other structural elements, and electronic structure changes due to the atomic reconstruction and superlattice effects. In a previous work (DOI:10.1088/2053-1583/aceb75), we studied the change of twisted bilayer (tBL) MoS<sub>2</sub> characteristics as a function of the twist angle, <em>θ</em>. We identified distinct structural regimes, each with particular structural and electronic properties. For 13°⪅<em>θ</em>⪅47°, the structure is well-described by a moiré regime composed of two rigidly twisted monolayers. At small twist angles (<em>θ</em>≤3° and 57°≤<em>θ</em>), a domain-soliton regime evolves, where the structure contains large triangular stacking domains, separated by a network of strain solitons and short-ranged high-energy nodes. </p> <p>The video files given in this repository show on their left side a top-view of the atomistic structure and on their right side the interlayer separation landscape of the respective area. The computational details are given in the related publication, the structure files are taken from the linked ZENODO repository. Video files are given for twist angles</p> <ul> <li>0° to 30°,</li> <li>0° to 60°,</li> <li>30° to 0°,</li> <li>30° to 60°, and</li> <li>60° to 30°.</li> </ul> <p>The video files are stored in two different bit rates, 4 Mbit/s, and 20 Mbit/s, as marked in the file names.</p>
