Tantalum diselenide is a compound made with tantalum and selenium atoms, with chemical formula TaSe₂, which belongs to the family of transition metal dichalcogenides. In contrast to molybdenum disulfide (MoS₂)^[1] or rhenium disulfide (ReS₂),^[2] tantalum diselenide does not occur spontaneously in nature, but it can be synthesized. Depending on the growth parameters, different types of crystal structures can be stabilized.

In the 2010s, interest in this compound has risen due to its ability to show a charge density wave (CDW), which depends on the crystal structure, up to 600 K (327 °C),^[3] while other transition metal dichalcogenides normally need to be cooled down to hundreds of kelvins or even below to observe the same capability.
