Condensed Matter Physics

Roughly speaking, when an atomic particle (electron) is emitted after the application of an electric field we are talking about field emission and a great part of the image devices produced by the industry are based in this physical effect. The recent discovery of the electronic propoerties of carbon nanotubes and other molecular nanowires has oppened a new age for the study of field emission mechanisms at the nano-scale.

In our department, at the University of Alicante, we are trying to implement the Non-Equilibrium Green's Function (or Keldysh) formalism, together with a localized description of unbound states, within our quantum transport package (ALACANT) in order to explain the emission mechanism of these novel emitters from first principles. This is particularly important in some applications like flat-panel displays and high-bias STM experiments where the tip-to-sample distance becomes so large and the electron current becomes a tunneling current.
