General Description

Rhenium disulfide (ReS₂) is a 2D layered semiconductor. ReS₂ unit cell is derived from hexagonal symmetry towards triclinic - a distorted 1T structure. An ReS₂ single layer is comprised of three atomic layers, 'S–Re–S', where Re and S are joined by covalent bonds and each rhenium is coordinated to six sulfur atoms in approximately octahedral geometry. Each sulfur atom is bonded to three Re atoms. Each Re atom also groups into parallelograms of four Re atoms, hence offering opportunities to introduce built-in planar anisotropy into composite heterostructures. 

Like other 2D layered materials, the adjacent layers in ReS₂ are also coupled by weak van der Waals (vdW) forces to form bulk crystals. Unlike most 2D layered materials, ReS₂ behaves as a stack of electronically- and vibrationally decoupled monolayers, even in the bulk form. Raman spectrum and photoluminescence properties are independent of the number of layers. This suggests that ReS₂ could offer a novel system to study mesoscopic physics of 2D systems without the limitation of obtaining large-area, monolayer-thick flakes.

Applications

Rhenium disulfide has peculiar physical properties: it exhibits distinct in-plane anisotropy and has a direct tunable optical band gap between 1.4 and 1.6 eV for both bulk and monolayer structures. Thus, ReS₂ layered nanostructures are good candidates for optoelectronic devices, photosensitive detectors, sensors, stretchable electrodes, and electrocatalysts applications. ReS₂ can also be employed to fabricate solar cell devices.

Synthesis

Rhenium disulfide (ReS₂) is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a purity in excess of 99.999%.

Usage

Rhenium disulfide single crystals can be used to prepare monolayer and few-layer ReS₂ by mechanical or liquid exfoliation.
