Molybdenum(IV) selenide Chemical Properties,Usage,Production

Description

Molybdenum(IV) selenide, also known as molybdenum diselenide, is an inorganic compound with the chemical formula MoSe2. It belongs to a group of compounds called transition metal disulfides (TMDCs), which are formed by combining a transition metal with an element from group 16 on the periodic table. MoSe2 has higher electrical conductivity than MoS2.

Chemical Properties

gray powder(s); used as a solid lubricant and lubricant film prepared by sputtering 99.9% pure material [HAW93] [STR93] [CER91]

Physical properties

The monolayer film of molybdenum diselenide, with a direct optical band gap of 1.48 eV and a photoluminescence peak at 840 nm, is highly suitable for optoelectronic applications. Moreover, when compared to MoS2, MoSe2 ultrathin films demonstrate a narrower bandgap, higher optical absorbance, and larger spin-splitting energy. These characteristics make MoSe2 films potentially superior to MoS2 for the utilization in tunnel FETs and optoelectronic devices.

Uses

Molybdenum chalcogenide thin film transitors for solar cells are a rapidly expanding area of research and molybdenum selenide compounds play an important role in this research. The layered nature of MoSe2 gives rise to several interesting applications such as field effect transistors ; piezoelectrics and substrates for self assembly

Definition

Available as a 40-micron powder.

Preparation

Mo and Se were mixed at a molar ratio of 1:2, and molybdenum and selenium reacted at a temperature of 800 to 1150°C to form mainly molybdenum diselenide(MoSe2). High-quality monolayer films of molybdenum diselenide were successfully grown directly on SiO2/Si substrates using the chemical vapor deposition (CVD) method.

Synthesis

Chemical exfoliation, utilizing N-methyl pyrrolidone (NMP) as a solvent, allows for the large-scale production of nano-particles and nano-sheets. This method enables the direct preparation of molybdenum diselenide (MoSe2) quantum dots from bulk powder of molybdenum diselenide.?
