Description and Uses
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.
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
