Keywords: technology of layers, vacuum thermal deposition, plasma deposition, thermal melting, inorganic materials, organic materials, hybrid materials, composite materials

Research team is experienced in formation of inorganic, organic, hybrid and composite layers and structures from solid state, material solutions and gaseous state using vacuum thermal deposition, spin, coating, casting and CVD processes.

Research group activities

The need for new optoelectronic devices aroused considerable interest.in technology of thin inorganic, organic, hybrid and composite material layers and, also, in 1D and 2D structures and materials. Aiming to address these problems and find a solution it is essential to understand how technology influences the formation of thin layers and interfaces and capacity to manage an intra– and interatomic bonds.

We investigate optical, electrical and structural features of deposited layers and structures and search for a new optoelectronic devices.

 

Proposal

  • Investigation and development of thin layer technologies and structures using various deposition methods: spin-coating and casting from solutions, vacuum thermal deposition, plasma deposition, thermal melting.
  • Investigate influence of deposition technology of variousm materials to density of local states in layers and interfaces by using optical, C-V, EPR spectroscopy, electrical and photoelectrical methods.
  • Investigate compatibility problems of layers of various materials and technologies.

 

We seek partners for developing competitive research projects targeting HORIZON 2020 and other international programs.
