· JVASP-5335· NbSe2Cl2

NbSe2Cl2 is a layered transition metal dichalcogenide compound combining niobium, selenium, and chlorine, belonging to the broader family of two-dimensional (2D) materials that can be exfoliated into atomically thin sheets. This is primarily an experimental research material rather than an established commercial product, investigated for its potential in nanoelectronics, optoelectronics, and energy storage applications where the weak interlayer bonding enables isolation of individual layers with modified electronic properties.
