Molybdenum Disulfide (MoS₂) Pristine Flakes in Solution, 100 ML

 

MoS₂ Pristine Flakes are nanoscale crystals dispersed in ethanol solution. If separated from the solution, nano-MoS₂forms emerald-green crystals that look different from the silver-black crystals of bulk MoS₂.

Properties:

• Lateral Size: 100-400 nm

• Thickness: 1-8 monolayers

• Purity in dry phase: >***

• Solution Concentration: 18 mg/L

• Solution is stable under ambient conditions

Each Mo(IV) center of MoS2 is occupying a trigonal prismatic coordination sphere, which is bound to six sulfide ligands. The sulfur centre is connected to three Molybdenum centres, which are pyramidal. The trigonal prisms are layered, sandwiching molybdenum atoms between layers of sulfur atoms.

Depiction of MoS₂ Crystal Structure¹

 

MoS₂ in its monolayer form has recently been under particular recognition for its intriguing electrical and optical properties. Bulk MoS₂ is generally an n-type semiconductor with an indirect bandgap (~1.3 eV) and a carrier mobility in the range of 50-200 cm² V^-1s^-1 at room temperature. On the other hand, monolayer MoS₂ has a direct bandgap of ~1.8 eV, and can be useful in low-power switching devices.
