Topological Weyl semimetal (TWS) is a metal, where low energy excitations behave like Weyl fermions of high-energy physics. It was recently shown that due to the lower symmetry of condensed matter systems, they can realize two distinct types of Weyl fermions. The type-I Weyl fermion in a metal is formed by a linear crossing of two bands at a point in the crystalline momentum space - Brillouin zone (BZ). The second type TWSs host type-II Weyl points appearing at the touching points of electron…

Quasiparticle interference on type-I and type-II Weyl semimetal surfaces: a review

Abstract Weyl semimetals are a new member of the topological materials family, featuring a pair of singly degenerate Weyl cones with linear dispersion around the nodes in the bulk, and Fermi arcs on

Searching for topological Fermi arcs via quasiparticle interference on a type-II Weyl semimetal MoTe2

Weyl semimetals display a novel topological phase of matter where the Weyl nodes emerge in pairs of opposite chirality and can be seen as either a source or a sink of Berry curvature. The exotic

Universal scattering response across the type-II Weyl semimetal phase diagram

The discovery of Weyl semimetals represents a significant advance in topological band theory. They paradigmatically enlarged the classification of topological materials to gapless systems while

Edelstein Effect in Type-II Weyl Semimetal WTe2 up to Room Temperature.

An outstanding feature of topological quantum materials is the current-induced spin polarization due to the unique spin-momentum locking (SML) characteristics of topological states. However,

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.

Visualizing superconductivity in an inversion-symmetry-broken doped Weyl semimetal

The Weyl semimetal MoTe$_2$ offers a rare opportunity to study the interplay between Weyl physics and superconductivity. Recent studies have found that Se substitution can boost the superconductivity

Unconventional Charge–Spin Conversion in Weyl‐Semimetal WTe2

A robust and practical method is demonstrated for electrical creation and detection of such a spin polarization using both charge-to-spin conversion and its inverse phenomenon and utilized it for efficient spin injection and detection in the graphene channel up to room temperature.

Experimental progress on layered topological semimetals

We review recent experimental progresses on layered topological materials, mainly focusing on transitional metal dichalcogenides with various lattice types including 1T, Td and 1T′ structural phases.

A Review of the Characteristics, Synthesis, and Thermodynamics of Type-II Weyl Semimetal WTe2

The crystal structure and characteristics of WTe2 are introduced, followed by a summary of the synthesis methods, and a comprehensive analysis and discussion are introduced to interpret the advantages, challenges, and future prospects.

Molecular beam epitaxy growth and strain-induced bandgap of monolayer 1T′-WTe2 on SrTiO3(001)

A monolayer 1T′-WTe2 film is grown on SrTiO3(001) with in-plane tensile strain. A height of ∼0.7 nm, obvious charge transfer, and incommensurate charge fluctuations in 1T′-WTe2 suggest strong
