1. Thermoelectric materials for improving energy efficiency

The aim of our computational studies is to discover new inorganic materials for improving energy efficiency via thermoelectric applications (direct conversion of waste heat to electricity). Our current research focuses on transition metal oxides and sulfides, oxide-organic superlattices, and semiconducting group 14 clathrates. The computational work is conducted in close collaboration with the Inorganic Materials Chemistry group of Prof. Maarit Karppinen.

2. New materials based on main group elements

New allotropes of main group elements are exciting both from the point of view of fundamental chemistry and prospective applications (for example, graphene and phosphorene). Within this topic we are collaborating closely with Prof. Thomas Fässler at Technical University of Munich and Dr. Lorenzo Maschio at University of Turin.

Another focus area within this topic is novel fluorine-based materials, which are being synthetized at the group of Prof. Florian Kraus (Philipps-Universität Marburg).

3. Photophysics and structural chemistry of organometallic luminophores

Efficient luminophores possess high application potential in areas such as electroluminescent devices, bioimaging, and nonlinear optical technologies. Our work in this area is based on a long-standing collaboration with the group of Prof. lgor Koshevoy at the University of Eastern Finland.
