二硒化鈦晶體（99.995%）/ 1T-TiSe2 (Titanium Selenide)

生產(chǎn)廠商：HQ Graphene

產(chǎn)品信息

TiSe2 (1T phase) is a semimetal. The 1T phase is a Charge density waves (CDW) system below ~200K. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Titanium Diselenide belongs to the group-IV transition metal dichalcogenides (TMDC). 
The TiSe2 crystals produced at HQ Graphene have a typical lateral size of ~0.8 cm, hexagonal shaped and have a metallic appearance. More information about the TiSe2 crystals we sell can be found below.
