Contents

In this topic, the use of density functional theory method together with the non-equilibrium Greens functions approach will be presented. This coupled approach can be used for calculating the electron transport across nanosystems. The details of this approach should be discussed. At a second level, examples of quantum transport simulations which deal with sensing schemes for DNA will be presented.
