Abstract

In this work we propose a cellular automata architecture using graphene nanoribbon arrays with spin polarization. We study the electronic and magnetic properties of the proposed structures by using first principles calculations and an algorithm based in the Glauber dynamic for simulating the cellular automata evolution. Our results show that the studied system can be scaled so that the propagation of digital information throughout the automata is possible at room temperature. © 2009 American Institute of Physics.
