CN2Si

Silicon carbodiimide is a metastable, wide-band-gap semiconductor material composed of silicon, carbon, and nitrogen.

Overview

About CN2Si

Silicon carbodiimide is a unique member of the nitride semiconductor family, characterized by its wide-band-gap electronic structure. As a metastable compound, it represents an intriguing target for materials synthesis and structural investigation within the broader landscape of carbon-nitrogen-silicon systems.

Its insulating nature and specific bonding arrangement make it a subject of interest for researchers exploring next-generation semiconductor materials. While it remains less common than established nitrides, its structural properties offer a distinct pathway for developing specialized electronic components.
