Gate-tunable quantum pathways of high harmonic generation in graphene
Soonyoung Cha, Minjeong Kim, Youngjae Kim +14
Under strong laser fields, electrons in solids radiate high-harmonic fields by travelling through quantum pathways in Bloch bands in the sub-laser-cycle timescales. Understanding t…
Photoluminescence Path Bifurcations by Spin Flip in Two-Dimensional CrPS4
Suhyeon Kim, Sangho Yoon, Hyo-Bin Ahn +6
Ultrathin layered crystals of coordinated chromium(III) are promising not only as two-dimensional (2D) magnets but also as 2D near-infrared (NIR) emitters owing to long-range spin…
Impact angle control of local intense d/d variations during shock-induced substorms
Denny M. Oliveira, James M. Weygand, Eftyhia Zesta +7
The impact of interplanetary shocks on the magnetosphere can trigger magnetic substorms that intensify auroral electrojet currents. These currents enhance ground magnetic field per…
γ-GeSe:a new hexagonal polymorph from group IV-VI monochalcogenides
Sol Lee, Joong-Eon Jung, Han-gyu Kim +12
The family of group IV-VI monochalcogenides has an atomically puckered layered structure, and their atomic bond configuration suggests the possibility for the realization of variou…
Strongly-bound excitons and trions in anisotropic 2D semiconductors
Sangho Yoon, Taeho Kim, Seung-Young Seo +9
Monolayer and few-layer phosphorene are anisotropic quasi-two-dimensional (quasi-2D) van der Waals (vdW) semiconductors with a linear-dichroic light-matter interaction and a widely…
Evidence of Higher Order Topology in Multilayer WTe from Josephson Coupling through Anisotropic Hinge States
Yong-Bin Choi, Yingming Xie, Chui-Zhen Chen +12
The noncentrosymmetric Td-WTe, previously known as a type-II Weyl semimetal, is expected to have higher order topological phases with topologically protected, helical one-dimen…
The role of momentum-dark excitons in the elementary optical response of bilayer WSe
Jessica Lindlau, Malte Selig, Andre Neumann +6
Monolayer (ML) transition metal dichalcogenides (TMDs) undergo substantial changes in the single-particle band structure and excitonic optical response upon the addition of just on…
Observation of Ultralong Valley Lifetime in WSe2/MoS2 Heterostructures
Jonghwan Kim, Chenhao Jin, Bin Chen +9
The valley degree of freedom in two-dimensional (2D) crystals recently emerged as a novel information carrier in addition to spin and charge. The intrinsic valley lifetime in 2D tr…
Electronic Structure, Surface Doping, and Optical Response in Epitaxial WSe2 Thin Films
Yi Zhang, Miguel M. Ugeda, Chenhao Jin +15
High quality WSe2 films have been grown on bilayer graphene (BLG) with layer-by-layer control of thickness using molecular beam epitaxy (MBE). The combination of angle-resolved pho…
Direct Observation of Layer-Dependent Electronic Structure in Phosphorene
