Low price, high purity 2D metal rhenium disulfide powder and crystals

For the development of next-generation electronics, optoelectronics, and nanotechnology

Rhenium disulfide (ReS₂, CAS number 12038-63-0) is a 2D layered semiconductor. 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.

Different Forms of Rhenium Disulfide

Sheets

Produce single or few-layer sheets

Rhenium disulfide is a direct band gap semiconductor that has exhibited outstanding optoelectronic performance due to its weak interlayer coupling. Compared to , ReS₂is a naturally-occurring yet extremely rare TMDC so it is environmentally stable which makes it an ideal candidate for applications in ambient conditions. ReS₂ has been found to be a diamagnetic semiconductor, an n-type photovoltaic material with a 1.4 eV optical gap, and exhibits bi-axial optical and electrical properties.

Bulk single rhenium disulfide crystal is most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation.

Rhenium disulfide powder can also be used to prepare ReS₂ nanosheets and nanoparticles by liquid-exfoliation (normally assisted by sonication), especially when it is the case of foreign elements such as lithium or sodium cations being inserted between layers by the process of intercalation. Liquid exfoliation can provide mass production of such products.

Structure of Rhenium Disulfide

ReS₂unit cell is derived from hexagonal symmetry towards triclinic - a distorted 1T structure. An ReS₂single 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 of the TMDCs, ReS₂ has an unique structure with its in-plane 1D chains of Re atoms. These are arranged into linked parallelograms - forming Re₄ “diamond” shapes along the b axis. Such a structure makes it an optically bi-axial material which shows exceptionally anisotropic electrical and optical behaviour for linearly-polarised light.

Properties of 2D Rhenium Disulfide

After exfoliation of crystal or powder, rhenium disulfide typically has the following properties:

ReS₂is a naturally-occurring yet extremely rare TMDC so it is environmentally stable
Triclinic distorted 1T structure (space group: P-1)
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
ReS₂ has been found to be a diamagnetic semiconductor, an n-type photovoltaic material with a 1.4 eV optical gap

Applications of Rhenium Disulfide

Rhenium disulfide single crystals can be used to prepare monolayer and few-layer ReS₂ by mechanical or liquid exfoliation. Rhenium disulfide powder is suitable for liquid chemical exfoliation to prepare ReS₂ nanosheets and nanoparticles down to few-layer films.

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 nanosheets and nanoparticles are also used for the fabrication of field-effect transistors, energy storage devices such as rechargeable batteries, photocatalytic and electrocatalytic hydrogen evolution reactions (HER). ReS₂ can also be employed to fabricate solar cell devices.

Exfoliated rhenium disulfide (ReS₂) nanosheets are shown to have a strong near-infrared (NIR) absorbance, and could effectively be used in biomedical applications, such as CT imaging and chemo-photothermal cancer treatment. High-purity rhenium disulfide powder is great for obtaining ReS₂ nanosheets by liquid exfoliation in mass production.

ReS₂ can also be employed to fabricate solar cell devices.

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.
