ceramic

· JVASP-4186· Te2Br

Te2Br is a layered halide ceramic compound composed of tellurium and bromine, belonging to the family of two-dimensional (2D) materials and van der Waals solids. This is a research-stage material primarily investigated for optoelectronic and electronic device applications rather than established industrial use. The material's layered structure and weak interlayer bonding make it a candidate for applications requiring exfoliation into thin sheets, positioning it as a potential alternative to graphene and transition metal dichalcogenides in emerging nanoelectronics, photonics, and quantum device research.
