MoWS2 high purity powder

Used to prepare quantum dot solutions and nano-platelets

Technical Data | MSDS | Structure | Literature and Reviews | Related Products | Resources and Support

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.

Molybdenum Tungsten Disulfide (MoWS2) Powder 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.

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.
