Rhenium Selenide

Rhenium Selenide Description

Rhenium selenide, also known as rhenium diselenide or diselenoxorhenium, is an inorganic compound with the formula ReSe2. It has a layered structure where atoms are strongly bonded within each layer. As most other dichalcogenides of transition metals, rhenium diselenide has a layered structure where atoms are strongly bonded within each layer and the layers are held together by weak Van der Waals bonds. However, while most other layered dichalcogenides have a high (hexagonal) symmetry, ReSe2 has a very low triclinic symmetry, and this symmetry does not change from the bulk to monolayers.

Rhenium diselenide has a stable distorted 1T phase (1T-ReSe2) in which the underlying 1D chain arrangement of Re4 parallelograms leads to a strong in-plane anisotropy. The structural distortion causes weaker interlayer coupling, which makes its bulk material behave electronically and vibrationally like decoupled monolayers.

Due to its distorted structure (like its twin ReS2), ReSe2 has also proven to exhibit dramatic spatial-anisotropy optical response, making it possible for applications in conceptual anisotropic optoelectronic and nanomechanical devices. The triclinic symmetry of the crystal lattice caused by the Re4 "diamond-shaped" parallelograms renders it optically bi-axial, giving the rise of an inherent anisotropic in-plane polarisation response. For this reason, ReSe2 and its doped hybrid materials are promising candidates for optical logic gates and optical computation.

ReSe2 devices exhibit an outstanding photoresponse to near-infrared light and field-effect transistors (FETs). Employing ReSe2 shows a p-type conduction characteristic with a current ON/OFF ratio of up to 105 and a hole-carrier mobility of 0.98 cm2V-1s-1.

Rhenium diselenide single crystals can be used to prepare monolayer and few-layer ReSe2 by mechanical or liquid exfoliation. Rhenium diselenide powder is suitable for liquid chemical exfoliation to prepare ReSe2 nanosheets and nanoparticles down to few-layer films.

Due to its reduced lattice symmetry, it also has potential applications in electronics, optoelectronics and thermoelectrics such as photodetectors, lasers and transistors.

ReSe2 has also a wide range of applications including strain sensors, stretchable electrodes, and flexible FETs, solar cells, and other photonic devices.
