Research - Applied Physical Chemistry & Molecular Nanotechnology

The Turchanin’s group focuses on novel two-dimensional (2D) materials, their hybrids and van der Waals heterostructures with functional physical and chemical properties. Topics include:

  • organic self-assembled monolayers
  • electron irradiation induced chemical reactions
  • carbon nanomembranes (CNMs) with molecular thickness
  • graphene and related 2D materials (e.g., MoS2)
  • carbon based electronics for nanosensing and energy storage
  • biofunctional surfaces and interfaces
  • nanolithography, ultramicroscopy and nanofiltration

The research activities concentrate on 2D carbon materials (graphene, carbon nanomembranes, organic monolayers) and their hybrids with other low dimensional materials for novel applications in nanoelectronics, nanosensors, energy-saving and nanobiotechnology. This interdisciplinary work embraces (i) growth of these materials with tailored physical and chemical properties [1-3], (ii) their nanolithography and microfabrication [4, 5], (iii) their implementation in novel functional nanostructures for both fundamental studies and applied research [6-7].

A novel route to ultrathin freestanding 2D carbon materials has been developed (see Fig. 1). Such an approach enables both generation of 2D materials with adjustable properties as well as their scalable production paving the way to a variety of applications in nanoscience and nanotechnology.
