Research topics


The main research interests are structural and electronic properties of various classes of materials and systems of strongly correlated electrons (e.g. metals, superconductors, organic and metal thin films, magnetic systems and charge density wave materials) by means of ultra-high vacuum (UHV) low temperature (LT) scanning tunneling microscopy (STM) and spectroscopy (STS). This includes initial stages of growth, surface reactivity and properties of surfaces and nanostructures between liquid helium (LHe) and room-temperature (RT), surface defects, surface electronic waves, individual adsorbed molecules and molecular structures, manipulation of individual atoms and molecules, and electronic properties of nonmagnetic and magnetic adatoms, including the Kondo effect.

We are also involved in the design and construction of a variety of LT UHV STM components, whose characteristics meet our special needs for some of the mentioned measurements. We are developing new experimental techniques with high spatial and energy resolution to study systems of strongly correlated electrons.
