Beschreibung
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.
Chemische Eigenschaften
gray powder(s); used as a solid lubricant and lubricant film prepared by sputtering 99.9% pure material [HAW93] [STR93] [CER91]
Physikalische Eigenschaften
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.
Verwenden
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 MoSe
2 gives rise to several interesting applications such as field effect transistors ; piezoelectrics and substrates for self assembly
Definition
Available as a 40-micron powder.
Synthese
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.?
