SPIN-VALVE DEVICES BASED ON GRAPHENE NANORIBBONS

摘要

PURPOSE: A spin valve factor using a graphene nano ribbon is provided to induce a spin polarization current with a small voltage by using the graphene nano ribbon with a wide width. CONSTITUTION: Ferromagnetic material electrodes(200,202) are connected to both ends of a graphene nano ribbon. The ferromagnetic material electrodes apply a current to the graphene nano ribbon. The graphene nano ribbon has a two-dimensional structure of a single layer made of carbon. The graphene nano ribbon is formed in a zigzag direction. The graphene nano ribbon is manufactured with a breadth less than 40nm. The ferromagnetic material electrodes arrange parallelly electrons at both edges of the graphene nano ribbon.
