Electronic transport in large systems through a QUAMBO-NEGF approach: Application to atomic carbon chains

► Graphene has many superior electronic properties. ► First-principles calculation are accurate but limited to system size. ► QUAMBOs construct tight-binding parameters with spatial localization, and then use divide-and-conquer method. ► SACC (single carbon atom chain): structure and transport show even-odd parity, and long chains are studied.
