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 

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 (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.
