Kramers Fulde-Ferrell state and superconducting spin diode effect
Yi Zhang, Ziqiang Wang
We study a novel Fulde-Ferrell equal-spin pairing state with opposite center of mass Cooper pair momentum for each spin polarization. This state respects time-reversal symmetry and…
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…
ARPES study of the epitaxially grown topological crystalline insulator SnTe(111)
Yi Zhang, Zhongkai Liu, Bo Zhou +8
SnTe is a prototypical topological crystalline insulator, in which the gapless surface state is protected by a crystal symmetry. The hallmark of the topological properties in SnTe…
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 Unusual Topological Surface States in Half-Heusler Compounds LnPtBi (Ln=Lu, Y)
Zhongkai Liu, Lexian Yang, Shu-Chun Wu +9
Topological quantum materials represent a new class of matter with both exotic physical phenomena and novel application potentials. Many Heusler compounds, which exhibit rich emerg…

Lexian Yang, Zhongkai Liu, Yan Sun +13
Three-dimensional (3D) topological Weyl semimetals (TWSs) represent a novel state of quantum matter with unusual electronic structures that resemble both a "3D graphene" and a topo…
Characterization of collective ground states in single-layer NbSe2
Miguel M. Ugeda, Aaron J. Bradley, Yi Zhang +14
Layered transition metal dichalcogenides (TMDs) are ideal systems for exploring the effects of dimensionality on correlated electronic phases such as charge density wave (CDW) orde…
Probing the Role of Interlayer Coupling and Coulomb Interactions on Electronic Structure in Few-Layer MoSe2 Nanostructures
Aaron J. Bradley, Miguel M. Ugeda, Felipe H. da Jornada +11
Despite the weak nature of interlayer forces in transition metal dichalcogenide (TMD) materials, their properties are highly dependent on the number of layers in the few-layer two-…
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…
