Excitons in a reconstructed moire potential in twisted WSe2/WSe2 homobilayers

Trond Andersen et al.

Summary: Recent advancements have allowed for direct imaging of stacking domains in van der Waals heterostructures, enabling a better understanding of the correlation between moire structures and electronic/optical properties. Through this technique, researchers were able to investigate reconstructed moire patterns in twisted WSe2/WSe2 bilayers and identify the emergence of distinct exciton species in photoluminescence measurements, with the ability to tune these states individually through electrostatic gating.

Strain fields in twisted bilayer graphene

Nathanael P. Kazmierczak et al.

Summary: Twisted bilayer graphene exhibits two-regime reconstruction mechanics based on twist angle, with applied heterostrain accumulating anisotropically in saddle-point regions to generate distinctive striped strain phases. Nanoscale spatial fluctuations in twist angle and uniaxial heterostrain were statistically evaluated, revealing the prevalence of short-range disorder in moire heterostructures. This study provides insights into the twist-angle-dependent electronic behavior and structural relaxation, disorder, and strain in moire materials.

Ab Initio Theory of Photoemission from Graphene

Eugene Krasovskii

Summary: Angle-resolved photoemission from monolayer and bilayer graphene is studied based on an ab initio one-step theory, showing a strong enhancement of emission intensity around scattering resonances. The effect of photoelectron scattering by the underlying substrate on the polarization dependence of the photocurrent is discussed. Experimental observations of the emission intensity are well reproduced within the dipole approximation.

Strain-Induced Quantum Phase Transitions in Magic-Angle Graphene

Daniel E. Parker et al.

Summary: Research on magic-angle twisted bilayer graphene reveals that small strain values can drive a zero-temperature phase transition between the symmetry-broken Kramers intervalley-coherent insulator and nematic semimetal. The critical strain falls within the experimentally observed range, suggesting that strain may partially account for sample-dependent experimental observations.

Flat band carrier confinement in magic-angle twisted bilayer graphene

Nikhil Tilak et al.

Summary: Researchers have demonstrated that flat bands in twisted bilayer graphene can amplify small doping inhomogeneity, leading to carrier confinement, a phenomenon previously only achievable in the presence of a strong magnetic field. This suggests that improving sample quality is crucial for studying electron physics in graphene.
