Molecular Materials/Organic Semiconductors

These are very challenging materials because intramolecular and intermolecular forces differ strongly in size but have to be described accurately. Recent focus of our group is on organic molecules that are considered in (opto-) electronics applications.

Additional research is dedicated to interesting open-shell systems.

2D Materials

Graphene and its friends appear in many forms (CVD, mechanical exfoliated, liquid-phase exfoliated, epitaxial, etc.). We have been looking at them from the charge transport perspective including fundamental questions such as weak localization phenomena or quantum Hall effect.
