WTe$_2$ is a layered transitional metal dichalcogenide (TMD) with a number of intriguing topological properties. The bulk crystal is a Weyl semimetal with Fermi arc surface states and the monolayer is a two-dimensional (2D) topological insulator. Recently, WTe$_2$ has also been predicted to be a higher-order topological insulator (HOTI) with hinge states along the edges. The gapless nature of WTe$_2$ complicates the observation of one-dimensional (1D) topological states in transport due to…

Observation of Edge States in Multilayer WTe2
Three-dimensional (3D) topological semimetals possess unconventional surface and edge states, which play central roles in exotic topological phases. WTe2, as a type-II Weyl semimetal, has 2D Fermi
Edge conduction in monolayer $WTe_{2}$
Experiments showing that a single layer of WTe2 can conduct electricity along its edges while insulating in the interior suggests that this material is a two-dimensional topological insulator. A
Evidence of higher-order topology in multilayer WTe2 from Josephson coupling through anisotropic hinge states
These experimental observations suggest a higher-order topological phase in WTe2 and its corresponding anisotropic topological hinge states, in agreement with theoretical calculations, and paves the way for the study of hinge states in topological transition-metal dichalcogenides and analogous phases.
Observation of topological states residing at step edges of WTe2
This study reports the direct observations of the topological states at the step edge of WTe2 by spectroscopic-imaging scanning tunneling microscopy and rigorously verifies the edge state has a topological origin, and its topological nature is unaffected by the presence of the substrate.
Gate-induced superconductivity in a monolayer topological insulator
Two groups show that the monolayer of the material tungsten ditelluride (WTe2)—already known to be a two-dimensional topological insulator—can also go superconducting and offers possibilities for gate-controlled devices combining superconductivity and nontrivial topological properties.
Pseudodoping of a metallic two-dimensional material by the supporting substrate
It is demonstrated how even weak hybridization with substrates can lead to an apparent heavy doping, using the example of monolayer 1H-TaS2 grown on Au(111), and the influence of pseudodoping on the formation of many-body states in two-dimensional metallic materials is analyzed.
Evidence for topological type-II Weyl semimetal WTe2
Exotic transport properties of type-II Weyl semimetals have been predicted but are yet to be experimentally evidenced and evidences of an anisotropy of negative magnetoresistance and a quantum oscillation arising from the predicted Weyl orbit in the type- II WeylSemimetal WTe2 are reported.
Ballistic edge states in Bismuth nanowires revealed by SQUID interferometry
It is shown that a magnetic field induces 0–π transitions and φ0-junction behaviour, providing a way to manipulate the phase of the supercurrent-carrying edge states and generate spin supercurrents.
Higher-Order Topology, Monopole Nodal Lines, and the Origin of Large Fermi Arcs in Transition Metal Dichalcogenides XTe_{2} (X=Mo,W).
This Letter calculates the bulk and surface electronic structure of β- and γ-MoTe_{2) and confirms that MNLSMs driven by double band inversion are the weak-spin-orbit coupling limit of HOTIs, implying that MN LSMs are higher-order topological semimetals with flat-band-like hinge states, which are found to originate from the corner modes of 2D "fragile" TIs.
Tuning magnetotransport in a compensated semimetal at the atomic scale
It is shown that reducing the thickness through exfoliation enables the electronic properties of WTe2 to be tuned, which allows us to identify the mechanisms responsible for the observed magnetotransport down to the atomic scale and indicate that atomically thin W Te2 layers remain gapless semimetals.
