FUTURE SENSOR TECHNOLOGIES

Advances in nanotechnology have led to the emergence of brand new materials. With the use of nanoscale materials with superior properties compared to the materials we have known for a long time, it will be possible to create sensors with extraordinary properties and equipped with brand new functions. With the experiments and theoretical studies we have carried out in our group, we investigate sensors from atomic scale properties to their possible applications.

GRAPHENE & ULTRA-THIN MATERIALS

In the near future, nanotechnology products obtained by combining atomic or molecular scale parts will become part of our everyday life. Therefore, investigation of the properties of nanoscale materials which will be the building blocks of nano devices is an important need in terms of ongoing technological studies. We perform theoretical and experimental studies on graphene and similar materials. Although these materials are one- or few-atom-thick they are quite stable and offer unique features.

PEROVSKITES FOR CLEAN ENERGY

Perovskite materials are promising candidates for the future optoelectronic technology. Conversion rate of sunlight into electricity is quite high for perovskite solar panels. In our team we mainly synthesize and characterize all-inorganic perovskites. For deeper understanding of their characteristic properties we also perform state-of-the-art ab initio calculations.
