Background and activities

My research area: Nanophotonic Materials and Devices 

In 2005 I was appointed as a full professor of nanophotonics as part of NTNU's strategic initiative in nanotechnology. At the Department of Electronic Systems my research focuses on synthesis and characterization of semiconductor nanowires for use in energy efficient light emitters and solar cells. Since 2015 a strong focus is being made on AlGaN nanowire ultraviolet (UV) LEDs grown on graphene. 

In 2010 I discovered and patented the growth of semiconductor nanowires on graphene originally shown for GaAs nanowires. This concept is schematically shown in this YouTube video https://www.youtube.com/watch?v=3wLOXHRVVwQ 

I am the inventor or co-inventor of 14 patent families with over 60 granted patents worldwide.

I am the founder and Chief Scientific Officer (CSO) of CrayoNano AS http://crayonano.com (founded in 2012) who are now developing germicidal UV LEDs using semiconductor nanowires on graphene substrates for use in water, air and surface disinfection applications.

I am an elected member of the Norwegian Academy of Technical Sciences (NTVA) since 2010.
