Description

Description 1T-VSe2 is a metallic and charge density wave (CDW) system with disproportionate CDW states below 110K. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. 1T VSe2 belongs to the group V transition metal dichalcogenides (TMDC).

Features And Benefits

Features And Benefits The 1T-phase VSe2 crystals produced at HQ Graphene have typical lateral dimensions of about 0.6-0.8 cm, are hexagonal and have a metallic appearance.

Application

Application The metallic properties of vanadium diselenide contribute to its potential for applications in supercapacitors and lithium-ion and sodium-ion batteries such as electrodes, moisture-detection sensors, and electrocatalysts for hydrogen revolution reactions (HER).
