▎ 摘　　要

A concept is presented that uses epitaxial graphene on silicon carbide (SiC) for digital circuits. It uses graphene as a metal and the underlying substrate SiC as semiconductor. On the base of transistors with excellent switching behavior, Inverter and NAND operation is demonstrated. [GRAPHICS] (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
