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

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

MoS₂ Pristine Flakes are nanoscale crystals dispersed in ethanol/water solution. If separated from the solution, nano-MoS₂ forms 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: >99%

Solution Concentration: 18 mg/L

Solution is stable under ambient conditions

UV-Visible Absorption Spectrum

Each Mo(IV) center of MoS2 is occupying a trigonal prismatic coordination sphere, which is bound to six sulfide ligands. The sulfur center is connected to three Molybdenum centers, 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.
