Supervisor’s research interests:

The scientific interests of the leader revolve around the interaction of optical radiation with condensed media, mainly with semiconductors. In the course of such an interaction in a solid, electron-hole pairs are generated, which eventually recombine into the ground state. In this case, several ways of such recombination are possible. One of them is radiative recombination in solids. Materials in which this is observed are good phosphors. This is the reason for the leader's interest in the study of hybrid (organo-inorganic) perovskites. Another way of recombination is through the external environment. Materials in which predominant recombination is observed by this mechanism often turn out to be active photocatalysts. This is the reason for the leader's interest in alkaline earth metal bismuthates and copper molybdates, as well as various heterostructures based on them. Semimetals are now distinguished into a separate class of materials. Typical representatives of such materials are MXenes, which, due to the large anisotropy of properties along one of the crystallographic axes, are promising spin conductors. This is the reason for the leader's interest in studying the issues of synthesis of MAX phases, obtaining MXenes from them and their further symmetric or asymmetric functionalization.

Supervisor’s specific requirements:

• For work on hybrid perovskites, a mandatory requirement is knowledge of methods of organic synthesis
• To work on maxenes, a mandatory requirement is knowledge of solid-phase synthesis methods
• For all destinations - a confident user of Origin
