The discovery of Mo6S3I6 molecular nanowires at the JSI in 2004 has lead to a great interest in these materials worldwide.The MoSIx molecular wire materials are of fundamental interest since they are grown as thin bundles of individual molecular wires where the interactions between them are exceptionally weak.This makes them probably the most one-dimensional material presently known.We have published more than 40 SCI publications on Mo6S3I6 material.The importance of these materials is also reflected in the investigation within three EU projects in the 6th framework programe.

The theory of self-organizations of charge carriers in high temperature superconductors is developed. A phase separation appears as a result of the interplay of the short-range attraction caused by the interaction with the lattice and the long-range Coulomb repulsion. Phenomenological theory of the effect is also developed. The theory of carrier relaxation in materials with a soft gap was developed. This theory was successfully applied to high Tc superconductors as well as to magnesium diborides and to heavy fermion compounds.

The study of complex functional matter using ultrafast spectroscopy have lead to a fundamental improvement in understanding of the dynamics of electronic, spin and lattice in these materials and the technique is now worldwide used for investigating new materials on ultrashort timescales.We have made large advances in femtosecond spectroscopy applying the method to different materials, one-and twodimensional chargedensity wave systems and in quasi-onedimensional orbitally-ordered JahnTeller system

For the study of electron dynamics in biological macromolecules our group has applied for the first time a method of photoinduced IR spectroscopy (PIA). The method consists of charge excitation by a laser pulse focused on a sample following by detection of a macromolecule's modified vibrational spectrum. We have identified prominent peaks in PIA spectra of DNA and their red spectral shift. We estimated the charge-vibration interaction strength. It has turned out that the charge-vibration interaction is too weak to cause a charge localization at room temperature and make a polaron state stable.

We established nanoelectronics as a new field in Slovenia. The effort was motivated by our need to measure transport properties in single MoSIx nanowires. We have set up e-beam nanolithography and can now routinely make circuits with features down to 100nm with reasonable success rates. The limiting factor is presently the stability of the electron microscope, which will be improved in the near future with the setting up of a new HRSEM. The first circuits have already produced results.In the next program period we expect new results from the use of this technique in molecular electronics.
