· JVASP-12026· NbSe2Br2

NbSe₂Br₂ is a layered transition metal dichalcogenide compound combining niobium, selenium, and bromine. This is an experimental material studied primarily in materials research rather than established industrial production; it belongs to the broader family of two-dimensional layered materials that have attracted attention for their unique electronic and mechanical properties. The material's low exfoliation energy suggests potential as a candidate for producing few-layer or monolayer sheets, which is of interest in next-generation electronics, optoelectronics, and energy storage research.
