Hierarchical Relaxation in Large-twist-angle Moire Drives Supermoire Formation
Chuqiao Shi, Giovanny Espitia, Yanxing Li +9
Supermoire lattices in large-angle twisted bilayers have recently been shown to emerge from periodic arrangements of commensurate stacking motifs, yet the microscopic structural me…

(Sub)nanoscale Visualization of Reconstruction-Driven Moiré Exciton Localization and Delocalization
Medha Dandu, Sriram Sankar, Giovanny Espitia +12
Spectral fingerprints in optical absorption and emission have typically been used as a signature of exciton localization in twisted moiré bilayers. However, the mechanism by which…

Quasi-one-dimensional taco-shaped bands in large-angle twisted bilayer transition metal dichalcogenides
Giovanny Espitia, Seung Hun Lee, Calvin Kaiyu Chiu +2
Two-dimensional moiré materials offer a powerful, twist-tunable platform for engineering electronic bands and correlations, though most studies to date have focused on small twist…
