- Wrinkles, Ridges, Miura-Ori, and Moiré Patterns in MoSe2
Effects of lateral compression on out-of-plane deformation of two-dimensional (2D) MoSe2 layers are investigated. A MoSe2 monolayer develops periodic wrinkles under uniaxial compression and Miura-Ori patterns under biaxial compression. The energetics, mechanical response, defect structure, and dynamics are analyzed as bilayers undergo wrinkle−ridge transformations under uniaxial compression and moiré transformations under biaxial compression. Our results indicate that in-plane compression can induce self-assembly of out-of-plane metasurfaces with controllable semiconducting and metallic phases and moiré patterns.
- Formation and Control of Ferroelectric Domains in Moiré MoS2
Moiré supercells, formed by the stacking of 2D van der Waals materials with small twists, have been shown to exhibit novel electronic and optical properties. These supercells have also been observed to give rise to a superlattice of out-of-plane ferroelectric domains. We examine how the initial twist angle of the stacked 2D materials affects the formation of ferroelectric domains and evolution of these domains with increasing temperature.
This research is carried in collaboration with Anikeya Aditya, Rajiv K. Kalia, Aiichiro Nakano and Ken-ichi Nomura of University of Southern California.
