Ab initio calculations of spin-nonconserving exciton-phonon scattering in monolayer transition metal dichalcogenides
Xiaowei Zhang, Ting Cao
We investigate the spin-nonconserving relaxation channel of excitons by their couplings with phonons in two-dimensional transition metal dichalcogenides using …
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…
Momentum-Dark Intervalley Exciton in Monolayer Tungsten Diselenide Brightened via Chiral Phonon
Zhipeng Li, Tianmeng Wang, Chenhao Jin +13
Inversion symmetry breaking and three-fold rotation symmetry grant the valley degree of freedom to the robust exciton in monolayer transition metal dichalcogenides (TMDCs), which c…
Inducing Metallicity in Graphene Nanoribbons via Zero-Mode Superlattices
Daniel J. Rizzo, Gregory Veber, Jingwei Jiang +7
The design and fabrication of robust metallic states in graphene nanoribbons (GNRs) is a significant challenge since lateral quantum confinement and many-electron interactions tend…
