MoWS2 high purity powder

Used to prepare quantum dot solutions and nano-platelets

Molybdenum tungsten disulfide (MoWS₂), CAS number 109657-36-5, is a transition metal dichalcogenide (TMDC) alloy. Alloying 2D TMDCs is an effective way of practically modulating the band gap. This is because alloys have good thermodynamic stability at room temperature.

Applications

Used to prepare quantum dot solutions and nano-platelets

Like molybdenum disulfide powder and tungsten disulfide powder, MoWS₂ powder has a layered hexagonal crystal structure. The bulk alloys are formed by stacking monolayer alloy together via van der Waals interactions. Each monolayer contains one MoW plane sandwiched by two S planes, represented as an S-MoW-S layer.

Structure of Molybdenum Disulfide Powder

Molybdenum tungsten disulfide structure — The crystal structure of molybdenum tungsten disulfide (MoWS₂)

Applications of Molybdenum Disulfide Powder

With a tunable band gap, band edge position, and carriers’ effective mass, thin-layer nanosheets of MoWS₂ have applications in electrochemistry and possess superior hydrogen evolution reaction performance. It has also been used in the development of high-performance optical switching, Q-switching, mode-locking, optical limiting, and optoelectronic devices.

Synthesis

Molybdenum tungsten disulfide powder is obtained via the CVT method, with purity typically in excess of 99.995%.

Usage

Molybdenum tungsten disulfide powder is generally used to prepare MoWS₂ quantum dot solutions and nano-platelets by liquid exfoliation assisted by sonication. High-purity MoWS₂ powder can also be used in CV deposition to prepare high-quality monolayer films.

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.
