ceramic

· Cd3AsI3

Cd₃AsI₃ is a ternary ceramic compound combining cadmium, arsenic, and iodine—a semiconductor material belonging to the family of chalcogenide and pnictide ceramics. This is primarily a research-phase compound studied for its potential optoelectronic and photonic properties rather than an established industrial material; the Cd-As-I system is explored in academic settings for semiconductor device development, particularly where tunable band gaps or specific light-matter interactions are required.
