Application

Owing to the thickness dependent physical and chemical properties, the two dimensional layered inorganic nanomaterials have drawn significant attention recently. They find applications in photocatalysis, phtotovoltaics, gas sensing, lithium ion batteries, field effect transistors, spintronics etc. Transition metal dichalcogenides represent an important class of inorganic 2D materials having aforementioned applications. The CVD grown monolayer films of MoS2, MoSe2, WS2 and WSe2 on insulating substrates such as SiO2 and sapphire are well suited for electronic and photovoltaic devices.

Caution

The material is air and moisture sensitive. Store under inert and moisture free condition.
