Untiedt's PicShort Biograhy.


I am an experimental physicist in the area of condensed matter. I am most interested in the properties of matter in the nanoscopic scale. There I have made most of my contributions in the study of electronic properties of atomic-sized contacts.

In this moment I am an associate profesor (Prof. Titular de Universidad) at the Nanophysics group of the Applied Physics Department in the Universidad de Alicante (Spain). Here I have founded the new Laboratory of Low Temperatures and Nanostructures where we did our first experiments on the spring of 2005.

Research interests


Currently I am involved in the following areas of research:
  • Molecular electronics. (More...)
  • Magnetism in atomic-sized structures
  • Chains of atoms (More...)
  • Magnetic nanowires (More...)
  • Mechanics and the atomic bond (More...)
  • Electrochemical formation of atomic-sized contacts


This research is made with the strong support of the rest of the nanophysics group of the applied physics department specially with Prof. Dr. Juanjo Palacios, Dr. Joaquin Fernandez-Rossier, M.J.Caturla and the Ph.D. students Reyes Calvo, Giovanni Sáenz, David Costa and Carlos Sabater.

Currently I also have collaborations with different groups in Europe:

  • Laboratorio de Bajas Temperaturas. UAM , Madrid (Spain). Here I made my Ph.D. My collaboration is specially with Prof. Dr. Nicolas Agraït, Prof. Dr. Gabino Rubio-Bollinger and Prof. Dr. Sebastian Vieira . They helped me to start the laboratory in Alicante. We collaborate in the areas of molecular electronics, chains of atoms and in the study of mechanics and the atomic bond.

  • Kamerling Onnes Laboratorium (web). Leiden (The Netherlands). Here I made three years of Post-doc with Prof. Dr. Jan van Ruitenbeek, working in close collaboration with R.H.M. Smit. We are currently collaborating in the areas of molecular electronics , magnetism in atomic-sized structures and chains of atoms. (more...)

  • Grupo de Física de Materiales Complejos (web). UCM, Madrid (Spain). With Prof. Jacobo Santamaria. We have recently started a line of collaboration to study magnetismin atomic-sized conductors and proximity effects in manganites.

  • Molecular Science Institute (web) UVA, Valencia (Spain). With Prof. Eugenio Coronado. We have recently started a line of collaboration within a CONSOLIDER project of the Spanish MEC to study magnetism in molecules deposited on flat surfaces.
Here is other people with whom I have or have had collaborative projects:

  • Universidad de Zaragoza. Zaragoza (Spain). With Dr. Fernando Luis I worked in the areas of magnetic nanowires.
    Karlsruhe Universiteit, Karlsruhe (Germany). With Dr. Juan Carlos Cuevas in the area of molecular electronics.
