Speaker Biography (Helge Weman)

Dr. Helge Weman is a professor in nanoelectronics at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. He received his PhD in semiconductor physics in 1988 from Linköping University, Sweden. During his career he has held various positions at UCSB (USA), NTT Optoelectronics Lab (Japan), EPFL (Switzerland), and IBM Res. Lab (Switzerland). Since 2005 Weman is leading a research group at NTNU on III-V semiconductor nanowires and graphene for use in optoelectronic applications. Weman has authored more than 100 refereed journal papers and is the inventor of six patent applications. In June 2012 he co-founded CrayoNano AS, where he is currently the Chief Technology Officer and Member of the Board.

Company Profile (CrayoNano AS)

CrayoNano AS logo
CrayoNano is developing optoelectronic devices based on semiconductor nanowires on graphene. This technology will enable smaller and more efficient optoelectronic devices for high growth markets like white LEDs, displays and solar cells. By using graphene as a combined electrode and substrate for the active nanowires the final devices become extremely thin and flexible that are able to absorb or emit large amounts of light from a small area using less material, making the CrayoNano technology platform the most efficient and cost effective standard for optoelectronic devices
