Cd2 Se2
semiconductor· Cd2 Se2
Cd₂Se₂ is a II-VI semiconductor compound composed of cadmium and selenium, belonging to the cadmium selenide family of materials. This material is investigated primarily in research contexts for optoelectronic and photovoltaic applications, where its direct bandgap and tunable electronic properties make it relevant for thin-film solar cells, photodetectors, and quantum dot-based devices. Cadmium selenide compounds are valued in niche high-performance applications where their optical absorption characteristics and carrier mobility outweigh concerns about cadmium toxicity and environmental regulations that increasingly limit their use in consumer electronics.
