Bulk MoS2 consists of stacked monolayers, which are held together by weak van der Waals interactions.

In both of these structures, each molybdenum atom exists at the center of a trigonal prismatic coordination sphere and is covalently bonded to six sulfide ions.

This facile method was first used by Konstantin Novoselov and Andre Geim to obtain graphene from graphite crystals.

However, it can not be employed for a uniform 1-D layers because of weaker adhesion of MoS2 to the substrate (either silicon, glass or quartz); the aforementioned scheme is good for graphene only.

A few methods include lithium intercalation[18] to delaminate the layers and sonication in a high-surface tension solvent.

While the pure MoS2 nanopillar fails through a plastic bending mechanism, brittle fracture modes become apparent as the material is loaded with increasing amounts of dopant.

[23] The widely used method of micromechanical exfoliation has been carefully studied in MoS2 to understand the mechanism of delamination in few-layer to multi-layer flakes.

[24] In recent years, MoS2 has been utilized in flexible electronic applications, promoting more investigation into the elastic properties of this material.

Nanoscopic bending tests using AFM cantilever tips were performed on micromechanically exfoliated MoS2 flakes that were deposited on a holey substrate.

[17] Molecular dynamic simulations found the in-plane Young's modulus of MoS2 to be 229 GPa, which matches the experimental results within error.

[6] Due to weak van der Waals interactions between the sheets of sulfide atoms, MoS2 has a low coefficient of friction.

Self-lubricating composite coatings for high-temperature applications consist of molybdenum disulfide and titanium nitride, using chemical vapor deposition.

[42] The catalyst can also effect hydrogenolysis of organosulfur compounds, aldehydes, ketones, phenols and carboxylic acids to their respective alkanes.

As in graphene, the layered structures of MoS2 and other transition metal dichalcogenides exhibit electronic and optical properties[48] that can differ from those in bulk.

[54][49][55] MoS2 nanoflakes can be used for solution-processed fabrication of layered memristive and memcapacitive devices through engineering a MoOx/MoS2 heterostructure sandwiched between silver electrodes.

In digital electronics, transistors control current flow throughout an integrated circuit and allow for amplification and switching.

In biosensing, the physical gate is removed and the binding between embedded receptor molecules and the charged target biomolecules to which they are exposed modulates the current.

[61] Due to the lack of spatial inversion symmetry, odd-layer MoS2 is a promising material for valleytronics because both the CBM and VBM have two energy-degenerate valleys at the corners of the first Brillouin zone, providing an exciting opportunity to store the information of 0s and 1s at different discrete values of the crystal momentum.

The Berry curvature is even under spatial inversion (P) and odd under time reversal (T), the valley Hall effect cannot survive when both P and T symmetries are present.

Therefore, monolayer MoS2 have been deemed an ideal platform for realizing intrinsic valley Hall effect without extrinsic symmetry breaking.

[63] MoS2 also possesses mechanical strength, electrical conductivity, and can emit light, opening possible applications such as photodetectors.
