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.

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 Structure

MoS2 in its monolayer form has recently been under particular recognition for its intriguing electrical and optical properties. Bulk MoS2is 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.
