· CeSiI

CeSiI is a layered ceramic compound composed of cerium, silicon, and iodine, representing an emerging material in the family of rare-earth halide semiconductors and layered silicates. This is a research-phase material currently being studied for potential applications in optoelectronics, photocatalysis, and low-dimensional materials science, where its layered structure and rare-earth chemistry offer opportunities for tunable electronic and optical properties distinct from conventional oxides or conventional semiconductors.
