Background and activities

My research area: Nanophotonic Materials and Devices 

My research at NTNU focuses on synthesis and characterization of semiconductor nanowires for use in energy efficient light emitters and solar cells. Fabrication of nanowire/graphene devices is being explored by electron beam lithography, nanoimprint and focused ion beam techniques. Opto-electronic characterization using techniques such as low temperature photocurrent and electroluminescence is done in order to understand and utilize these nanowires in future photonic device applications. Since 2015 a strong focus is being made on AlGaN nanowire UV LEDs grown on graphene. 

In 2010 I discovered and patented the growth of III-V semiconductor nanowires on graphene originally shown for GaAs nanowires, as schematically shown in this viral YouTube video https://www.youtube.com/watch?v=3wLOXHRVVwQ 

I am the inventor or co-inventor of 14 different patent families with over 50 patents granted worldwide.

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

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