“…While the monoclinic 1T′ phase has the centrosymmetric space group P2 1 / m , the orthorhombic T d phase has two possible space groups, the non‐centrosymmetric P mn 2 1 and the centrosymmetric P nmm . The P mn 2 1 T d phase TaIrTe 4 is predicted to host just four type‐II Weyl points, the minimal number of Weyl points hosted by a system with time‐reversal invariance . Intensive efforts have been made to search for the related effects of the broken inversion symmetry and the type‐II Weyl nodes of the material .…”

The layered ternary compound TaIrTe is an important candidate to host the recently predicted type-II Weyl fermions. However, a direct and definitive proof of the absence of inversion symmetry in this material, a prerequisite for the existence of Weyl Fermions, has so far remained evasive. Herein, an unambiguous identification of the broken inversion symmetry in TaIrTe is established using angle-resolved polarized Raman spectroscopy. Combining with high-resolution transmission electron microscopy, an efficient and nondestructive recipe to determine the exact crystallographic orientation of TaIrTe crystals is demonstrated. Such technique could be extended to the fast identification and characterization of other type-II Weyl fermions candidates. A surprisingly strong in-plane electrical anisotropy in TaIrTe thin flakes is also revealed, up to 200% at 10 K, which is the strongest known electrical anisotropy for materials with comparable carrier density, notably in such good metals as copper and silver.

“…Moreover, combining twist with strain can suppress Dirac cone and also lead to the emergence of the flat band in heterostrain systems . The TMDs MX 2 (M = W, Mo and X = S, Se, Te) demonstrate unique optical, electronic, and topological properties in traditional AB‐stacked phase. Understanding the electronic properties of stacked 2D twisted multilayer TMDs is critical.…”

The electronic properties of the twisted transition metal dichalcogenide MoTe2 through first‐principles calculations are investigated. The interlayer interaction is corrected by van der Waals correction. Some local stable twisted configurations are obtained by calculating the interlayer binding energy as a function of twist angle. The calculations indicate that the size of bandgap is dependent on the twist angle, and a transition from indirect to direct bandgap semiconductor is identified for both bulk and bilayer twisted 2H‐MoTe2. The uniaxial compression significantly changes the bands and results in a phase transition from the original semiconductor to metal. Under uniaxial tensile, the valence‐band maxima (VBM) change from the Brillouin zone (BZ) center point Γ to the BZ face center point M. Interestingly, a phase transition from the semiconductor to metal is identified under both biaxial compression and tensile. The VBM, conduction‐band minima, and the orbital components around the Fermi level demonstrate a dramatic change under biaxial strain, which leads to a great change in optical and electronic transport properties of twisted MoTe2. These results are useful for the understanding of the electronic properties of twisted systems and the applications of twisted layered materials in future electronic devices.
