V₂NiSe₄ (Vanadium Nickel Selenide)

V₂NiSe₄ is a ternary layered selenide with the nominal formula V₂NiSe₄, a van der Waals crystal combining vanadium and nickel. Its layered structure makes it suitable for exfoliation-based studies of mixed-metal chalcogenides.

Growth method: Chemical vapor transport (CVT).

Sample specifications: Individual crystals measure approximately 3–4 mm, with a purity of up to 99.999% (5N), and 2–3 high-quality single-crystal pieces included in each package.

Exfoliation: Easy — readily cleaved into thin flakes by standard mechanical exfoliation.
