Research Interests

Dr. Zakhidov’s research is focused on the comprehensive study of organic semiconductors including: fundamentals, processing, mechanisms and applications in optoelectronics. Particular topics of interest, include:

  • Organic light emitting diodes (OLEDs) for displays and lighting
  • Perovskite photovoltaic devices (solar cells and photodiodes)
  • Organic thin film transistors (OTFTs) and circuits
  • Organic micro-cavities and organic lasers
  • Nano-carbon (carbon nanotubes and graphene) electrodes
  • Molecular doping
  • High-resolution structuring of organic semiconductors

Dr. Zakhidov pioneered orthogonal micro- and nano-fabrication technique for organic semiconducting structuring and processing. This method essentially enables fundamental nano-science of organic electronic devices as well as their heterogeneous integration with the state of the art traditional electronics.
