Evidence for a spinon Kondo effect in cobalt atoms on single-layer 1T-TaSe
Yi Chen, Wen-Yu He, Wei Ruan +13
Quantum spin liquids (QSLs) are highly entangled, disordered magnetic states that arise in frustrated Mott insulators and host exotic fractional excitations such as spinons and cha…
Imaging spinon density modulations in a 2D quantum spin liquid
Wei Ruan, Yi Chen, Shujie Tang +17
Two-dimensional triangular-lattice antiferromagnets are predicted under some conditions to exhibit a quantum spin liquid ground state whose low-energy behavior is described by a sp…
Observation of Topologically Protected States at Crystalline Phase Boundaries in Single-layer WSe2
Miguel M. Ugeda, Artem Pulkin, Shujie Tang +12
Transition metal dichalcogenide (TMD) materials are unique in the wide variety of structural and electronic phases they exhibit in the two-dimensional (2D) single-layer limit. Here…
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…
Observation of charge density wave order in 1D mirror twin boundaries of single-layer MoSe2
Sara Barja, Sebastian Wickenburg, Zhen-Fei Liu +13
Properties of two-dimensional transition metal dichalcogenides are highly sensitive to the presence of defects in the crystal structure. A detailed understanding of defect structur…
Observation of giant bandgap renormalization and excitonic effects in a monolayer transition metal dichalcogenide semiconductor
Miguel M. Ugeda, Aaron J. Bradley, Su-Fei Shi +9
Two-dimensional (2D) transition metal dichalcogenides (TMDs) exhibit novel electrical and optical properties and are emerging as a new platform for exploring 2D semiconductor physi…
