Abstract

Memristors and Memristive Devices were idealized nearly 40 years ago, but were properly characterized in an experiment only in 2008. Those devices are attractive candidates to provide a paradigm change in volatile and non-volatile memory devices fabrication. These memory devices would be faster, denser and more enduring than the devices available today, but their immediate fabrication is not yet possible, due to the lack of understanding about their operation at the atomic level. In this project we aim to study the raw materials both separately and together using ab initio state-of-the-art techniques as DFT and Green function out-of-equilibrium formalism transport in order to contribute to the understanding of the electronic structure, configuration of atoms and electronic transport of these systems at a fundamental level.
