Academic Interests


To understand the basic physics of materials from the point of the atomic scale. We do that by theoretically model and calculate complex material structures. The intention is to desig materials for the use in primarily renewable energy technologies, such as solar cells, LEDs, and thermoelectric devices. The physics at the interface between two materials is very important to analyze the electron, ion, and heat transport in these devices. By understanding the fundamental physics of materials, we can propose new, inexpensive, environmental-friendly, and efficient materials. Thus, we are involved in the development of future energy technologies.

We use world-leading and very powerful computer program to calculate the fundamental properties of materials (Wien2k, VASP, Exciting). We are also involved in developing the software in order to studying new material properties. These computer programs are theoretical tools in our studies. The research is focused on analyzing different types of material structures to obtain both broad and deep theoretical understanding of materials at the atomic level to micrometer scale.
