Distilling universal machine-learning potentials for moiré lattices across one million atoms
Thomas Huang, Yueyao Fan, Kaichen Xie +7
Atomic reconstruction reshapes moiré materials across multiple scales, from local structure and polarization textures to global electronic topology, yet direct \textit{ab initio} m…
Uniaxial plasmon polaritons charge transfer at the graphene/CrSBr interface
Daniel J. Rizzo, Eric Seewald, Fangzhou Zhao +24
Graphene is a privileged 2D platform for hosting confined light-matter excitations known as surface plasmon-polaritons (SPPs), as it possesses low intrinsic losses with a high degr…
Designing magnetic properties in CrSBr through hydrostatic pressure and ligand substitution
Evan J. Telford, Daniel G. Chica, Kaichen Xie +10
The ability to control magnetic properties of materials is crucial for fundamental research and underpins many information technologies. In this context, two-dimensional materials…
Phonon-mediated exciton relaxation in two-dimensional semiconductors: selection rules and relaxation pathways
Xiao-Wei Zhang, Kaichen Xie, En-Ge Wang +2
Exciton-phonon coupling (ExPC) is crucial for energy relaxation in semiconductors, yet the first-principles calculation of such coupling remains challenging, especially for low-dim…
Interlayer Electronic Coupling on Demand in a 2D Magnetic Semiconductor
Nathan P. Wilson, Kihong Lee, John Cenker +10
When monolayers of two-dimensional (2D) materials are stacked into van der Waals structures, interlayer electronic coupling can introduce entirely new properties, as exemplified by…
