Research Interests

Materials science, inorganic chemistry, 2D materials, nanoelectronics, sensors

I'm a material scientist, focused on exploration of properties and applications of low-dimensional materials like graphene, GO, MoS2, TiS3, MXenes. I have an expertise in 2D materials' synthesis, nanofabrication, electrical measurements, and characterization by various methods. My current projects include:

  • Investigation of memory properties of heterostructures based on 2D materials and ferroelectrics with vertical (FTJs) and horizontal (FE FETs) transport;
  • Exploration of properties of gas sensor arrays (e-nose) based on graphene, reduced graphene oxide and TiS3;
  • Characterization of electrical and structural properties of other low dimensional materials, namely MXenes and quasi-one dimensional TiS3;
  • Probing graphene materials as a protective layer (coatings, membranes) for nanostructures and other materials. This also includes covering graphene with polymers.
