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…
Long-range transport of 2D excitons with acoustic waves
Ruoming Peng, Adina Ripin, Yusen Ye +9
Excitons are elementary optical excitation in semiconductors. The ability to manipulate and transport these quasiparticles would enable excitonic circuits and devices for quantum p…
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…
Spin Photovoltaic Effect in Magnetic van der Waals Heterostructures
Tiancheng Song, Eric Anderson, Matisse Wei-Yuan Tu +9
The development of van der Waals (vdW) crystals and their heterostructures has created a fascinating platform for exploring optoelectronic properties in the two-dimensional (2D) li…
Imaging graphene moiré superlattices via scanning Kelvin probe microscopy
Junxi Yu, Rajiv Giridharagopal, Yuhao Li +5
Moiré superlattices in van der Waals heterostructures are gaining increasing attention because they offer new opportunities to tailor and explore unique electronic phenomena when s…
Electric Field Tunable Topological Phases in Graphene Nanoribbons
Fangzhou Zhao, Ting Cao, Steven G. Louie
Graphene nanoribbons (GNRs) possess distinct symmetry-protected topological phases. We show, through first-principles calculations, that by applying an experimentally accessible tr…
