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…
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…
