General Description

Titanium disulfide (TiS2) is a semimetal with an indirect band-overlap of about 0.12 eV. It has been successfully employed as an electrode material for rechargeable sodium and lithium ion batteries.

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.


Monolayer titanium disulfide is the lightest member of the transition metal dichalcogenide family. It has promising applications in energy conversion and storage systems. 2D titanium disulfide has also been used in non-linear optics, supercapacitors, and ultrafast fiber laser applications.


Titanium disulfide is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a purity in excess of 99.999%.


Titanium disulfide single crystals can be used to prepare monolayer and few-layer TiS2 by mechanical or liquid exfoliation.
