Hf2 Si2 Se2
semiconductor· Hf2 Si2 Se2
Hf₂Si₂Se₂ is a layered ternary semiconductor compound combining hafnium, silicon, and selenium in a stoichiometric composition. This material belongs to an emerging class of van der Waals heterostructures and layered semiconductors being explored primarily in research settings for next-generation optoelectronic and electronic devices. The hafnium-silicon-selenium family is investigated as a potential alternative to conventional two-dimensional materials, with interest driven by tunable bandgap engineering, thermal stability, and integration potential in nanoelectronic applications.
