Twin Irida Graphene: A Carbon Material with Optoelectronic Features

Abstract A novel allotrope structure of carbon named twin irida graphene composed of 3‐16‐8 carbon rings is proposed. Its structural, mechanical, electronic, and optical characteristics are explored by density functional theory. It is shown that twin irida graphene has an energetically favorable structure. Its dynamical and thermal stabilities at room temperature are also examined and confirmed. The in‐plane stiffness of twin irida graphene is less than graphene. It is a metal and maintains this property even against the external strain and applied electric field. This sheet exhibits an anisotropy response to the incident photon with different polarizations. The potential of sheet for use in energy storage and absorption systems is indicated by its high dielectric constant and optical absorption. The reflection constants as well as the transmission constants of twin irida graphene indicate its transparency, mostly in the high‐energy region. Thus, twin irida graphene is a suitable material for use in optoelectronic applications due to its structural and physical characteristics.
