Titanium(IV) sulfide (also known as titanium disulfide TiS2), CAS number 12039-13-3, is highly stable. It is the most lightweight and low-cost Group IV TMDC material. TiS2 is known to be a semimetal in when in bulk form with an indirect band-overlap of about 0.12 eV, and a semiconductor when strain or pressure is applied in the monolayer form. With a higher degree of overlap of the valence and conduction bands, its semi-metallic nature intensifies when compression is applied. However, the energetic overlap is lifted and a semimetal-to-semiconductor transition occurs under pressure or strains.

Different Forms of Titanium(IV) Sulfide

TiS2 crystallises in an octahedral (1T) phase, which is more energetically stable compared to its hexagonal (2H) phase. Titanium(IV) sulfide has been successfully employed as an electrode material for rechargeable sodium and lithium ion batteries.

We supply low price titanium(iv) sulfide in several different forms for a range of applications.

*Typical representative size, areas/dimensions may vary

Bulk single titanium(IV) sulfide crystal is most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation.

Titanium(IV) sulfide powder can also be used to prepare TiS2 nanosheets and nanoparticles by liquid-exfoliation (normally assisted by sonication).

Structure of Titanium(IV) Sulfide

A single sheet of TiS2 is formed by a titanium atom layer sandwiched between two layers of sulfur atoms that are covalently bonded to the titanium atoms. Like other Group IV transition metal dichalcogenides, TiS2 crystallises in an octahedral (1T) phase, which is more energetically stable compared to its hexagonal (2H) phase.

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.
