Abstract

Memristors and Memristive Devices have been predicted nearly 40 years ago, but it was only in 2008 that such devices were characterized in laboratory. These devices are strong candidates to change the paradigm of memory devices, either volatile and non-volatile storage systems. This would be achieved by the possibility of manufacturing denser, faster and better-enduring devices than those available today. Its immediate application is, however, hindered by the lack of understanding about its working principle, specially at atomic level. In this project we have a clear objective: using state-of-the-art ab initio techniques such as Density Functional Theory and electronic transport codes based on non-equilibrium Green's functions, we seek to study the raw materialsused to build these devices either separately and together as close as possible to the actual device, and in this way contribute to the understanding of the electronic structure, atomic arrangement and electronic transport mechanisms of memristors at its basic level.
