Research Focus Areas: Electronic and Photonic Devices

The Nano-Optoelectronic Materials and Devices Laboratory focuses on developing high-performance nanophotonic devices using nanostructures and their applications in a variety of areas, including light-emitting diodes, laser diodes, solar cells, as well as in solar-fuel cells.


Our research research expertises cover the epitaxial growth, device fabrication and characterization of III-V based self-organized nanostructure materials grown by molecular beam epitaxy. Our research topics are listed below:

  • Semiconductor nanostructures for nanoelectronics and optoelectronics
  • Epitaxial growth and characterization of III-nitride nanostructures
  • III-V based materials and devices
  • Light emitting diodes, laser diodes, photodetectors
  • Solar fuels, solar cells
