· JVASP-10571· RbSb2Se4

RbSb2Se4 is a layered chalcogenide ceramic compound composed of rubidium, antimony, and selenium elements. This material belongs to the family of van der Waals layered semiconductors and is primarily studied in research contexts for its potential in optoelectronic and thermoelectric applications. The weak interlayer bonding characteristic of this material class makes it of particular interest for applications requiring exfoliation into two-dimensional nanosheets or thin films, positioning it as a candidate material for next-generation energy conversion devices, photodetectors, and layered heterostructure engineering.
