Nanomaterials

Laboratory for nanomaterials

In the Laboratory for nanomaterials the efforts of our research are focused on study of fundamental and applied aspects of nanosystems and nanostructured materials, formed using ion and cluster beams. Both top-down and bottom-up strategies are followed with a key question of how surface and embedded nanostructures can be formed and modified at will to acquire the desired properties and functionality? For this, advantages offered by cluster and ion beams for manipulation with matter at the nanoscale are applied for materials modification, synthesis, characterization and functionalization.

Cluster self-organization and aggregation on the surface, thermal, structural, electrical and magnetic properties are in the focus of the Lab activity. An urgent need for successful nanoelectronic applications in comprehensive understanding of size- and spin-dependent quantum effects, mesoscopic transport, thermal and mechanical properties of low-dimensional structures (thin films 2D, nanowires 1D and nanoparticles 0D) are addressed.

In the Laboratory for nanomaterials the following experimental techniques are available:

  • Ion implantation

  • Dual e-beam and ion sputter deposition
  • Ion beam dry etching facility for nanostructuring and downsizing
  • Atomic Force Microscopy (AFM) / Scanning Tunneling Microscopy (STM)
  • Low Energy Electron Diffraction (LEED)
  • Auger Electron Spectroscopy (AES)
  • Low Energy Ion Deposition (LEID, under development)
  • Ultra-High Vacuum (UHV) Variable Temperature Atomic Force Microscope (AFM) / Scanning Tunneling Microscope (STM)
  • Cryogen-Free Dilution Refrigerator System (~10mK)
  • Furnaces for sample annealing (up to 1500 ℃)
  • Equipment for terahertz spectroscopy
