My present activities in Micronova Research Center focus mostly on nanotechnology and nanostructures based on advanced materials which are used in nanoelectronic and photonic devices. Micronova forms the major part of the national OTANANO research infrastructure. My current research topics include

• graphene and other 2D materials (CVD fabrication and devices), see e.g. http://graphene-flagship.eu
• semiconductor nanowires, see e.g.  http://www.iet.ntnu.no/projects/nanordsun/
• energy efficiency especially in advanced LEDs and solar cells, see http://energyefficiency.aalto.fi/en/research/moppi/
• nanofabrication by atomic layer deposition, MOCVD, electron beam lithography, self-assembly etc.
• devices based on semiconductors (GaN, GaAs, InP, Si...) and their nanostructures (quantum dots and wires, black silicon...), e.g. LEDs, x-ray detectors, SERS sensors, THz emitters and detectors
• functional surfaces and thin films (such as passivation and wetting properties)
• quantum effects in nanostructures
• materials characterization (optical spectroscopy, Raman mapping, AFM, SEM. XRD, XRR, electrical measurements)
