RESEARCH

The main focus of the work is divided into three big groups. The first one is preparation of chalcogenide glasses in form of bulk glasses (Ag-As-Se) or thin films (Ag-As-Se, Ge-Sb-Te-Se) and their characterisation for application as a material for memories.
The second one is preparation of graphene oxide and reduced graphene oxide and its study as a possible material for gas sensors.
The third group is connected to transition metal dichalcogenides their exfoliation and building of different heterostructures for optical measurement at low temperature and under applied magnetic field.
