Molybdenum disulfide crystal, one of the most studied and celebrated TMDCs

Widely used as a high performance lubricant

Molybdenum disulfide (MoS2) is a member of the transition metal dichalcogenides (TMDC) family. Due to its natural availability as molybdenite, it is one of the most studied and celebrated TMDCs.

Like graphene, MoS2 has a similar two-dimensional layered structure - with each individual layer stacked upon each other to form the bulk single crystal. Each layer of MoS2 is composed of a plane of hexagonally-arranged molybdenum atoms, positioned between two planes of hexagonally-arranged sulfur atoms. Like graphite, each layer is bound by weak van der Waals forces. Because of this, it is possible to obtain monolayer to few-layer crystal flakes from a bulk crystal via mechanical exfoliation (using scotch tape).

Applications of Molybdenum Disulfide Crystal

MoShas an indirect band-gap of 1.23 eV for bulk single crystal or multi-layer films. However, single atomic layers have a direct band-gap of 1.9 eV. Due to its layered structure, MoS2 is highly anisotropic with excellent nonlinear optical properties. It is widely used as a high-performance lubricant.

As a result of its direct band-gap, single-layer MoS2 has received much interest for applications in electronic and optoelectronic devices (such as transistors, photodetectors, photovoltaics and light-emitting diodes). It is also being explored for applications in photonics, and can be combined with other TMDCs to create advanced heterostructured devices.


Molybdenum disulfide MoSis manufactured via chemical vapour transport (CVT) crystallisation, with purities of over 99.999% achieved.


Molybdenum disulfide MoS2 is used to create monolayer and few-layer MoS2 by mechanical or liquid exfoliation. Single crystals can also be studied using a range of microscopies (including AFM and TEM).
