Technical Data | MSDS | Structure | Literature and Reviews | Related Products | Resources and Support

Tungsten ditelluride (WTe2), CAS number 12067-76-4, is a combination of the heaviest element in the common transition metal dihalcogenides (TMDCs) and a non-magnetically-thermoelectric semimetal (with reduced density of states at the Fermi level).

2D-layered tungsten ditelluride (WTe2) has recently received great research interest for its unique, non-saturating, and extremely large positive magnetoresistance (XMR) behaviour. With perfectly balanced electron-hole populations, this particular non-saturating XMR identified applications for WTe2 in information processing and storage devices.

Td-WTe2 was the first material proposed to be a type II Weyl semimetal, with a reduced density of states at the Fermi level coming from a small overlap between valence and conduction bands without a band gap. It has been reported that even single and dual-layer WTe2 films preserve the semimetallic nature, and both the films have equal hole and electron carrier concentrations. Additionally, WTe2 has been reported to exhibit pressure-induced superconductivity.

Bulk single tungsten ditelluride crystal is most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation. Single tungsten ditelluride crystal or films produced from such crystals are suitable for study using atomic force microscopy or transmission electron microscopy.

Few-layer WTe2 nanosheets and nanoparticles can also obtained from tungsten ditelluride powder by liquid-exfoliation using sodium deoxycholate bile salt as surfactant. Topological Superconductivity can also be realised in potassium intercalated Td-WTe2.

Structure of Tungsten Ditelluride 

Distorted Td-WTe2 has proven to be the stable form over its semiconducting 2H-WTe2 structure. The distortion is induced by the tungsten chains that are arranged along the a axis of the orthorhombic unit cell. Electrical resistance along the a axis increases markedly when a magnetic field is applied perpendicularly to the dichalcogenide layers (along the c axis), resulting in the large magnetoresistance (LMR) effect.

In ambient conditions, WTe2 crystallises in a orthorhombic lattice - where tungsten atoms are coordinated by tellurium atoms in an octahedral environment. The unit cell contains two Te-W-Te layers (held together by van der Waals interaction), with one sheet rotating 180 with respect to the other. This stacking sequence is referred to as a 'distorted 1T (Td) structure.

Viscoelastic Transfer of 2D Material Using PDMS

Viscoelastic transfer using polydimethylsiloxane (PDMS) stamps is one of the methods used for the deterministic placement of 2D materials and the fabrication of van der Waals heterostructures. It relies on the viscoelasticity of PDMS, which behaves as an elastic solid on short time scales, but as a viscous fluid on long time scales.
