title = "The study on structure and electronic property of amorphous carbon using density functional theory",
abstract = "Amorphous carbon (a-C) has become a promising material applied for optoelectronic devices. The requirement parameter that should be considered to develop the device is the electronic property of the structure composed. a-C materials are composed of a hybridization mixture of sp2 and sp3 orbitals. The new characteristic possessed by a-C must be studied to investigate its electrical properties. In this paper, the density functional theory (DFT) using Quantum Espresso package has been applied to generate and analyze the density of state and band structure of a system. Here, the amorphous structure of carbon is modeled to be a combination between one unit cell of graphene with sp2 hybridization and 2-unit cells of diamond, with sp3 hybridization. The result shows that the electronic property of the a-C proposed behaves as metal, which is experimentally supported by the electrically conductive properties of sp2-hybridization carbon.",
