Nanoscience and Advanced Materials

The Nanoscience and Advanced Materials group is part of the Department of Electronics and Nanoengineering, Aalto University. The group is located in the nanofabrication research center Micronova and has about 15 researchers. The group hosts Tekes-funded FiDiPro (Finland Distinguished Professor) Nasser Peyghambarian from University of Arizona jointly with University of Eastern Finland. Research is mainly funded by external sources, especially the National Technology Agency (Tekes), the Academy of Finland, EU, ESA and industry.
Nanotechnology Group

The group focuses in the research of nanomaterials, nanostructures and advanced materials for use especially in nanoelectronics and nanophotonics. Areas of current research activities include

  • graphene and related 2D materials including CVD fabrication and devices). The group participates in the EU Graphene Flagship project, see http://graphene-flagship.eu/
  • compound semiconductor nanowires
  • energy efficiency especially in advanced LED and solar cell concepts. The group is involved in the Aalto Energy Efficiency program, see http://energyefficiency.aalto.fi/en/research/moppi/
  • nanofabrication by atomic layer deposition (ALD), metalorganic chemical vapour deposition (MOCVD), electron beam lithography, focused ion beam lithography, self-assembly etc.
  • micro-, nano- and optoelectronic devices based on semiconductors (GaN, GaAs, InP, Si...) and their nanostructures (such as quantum dots, nanowires and black silicon). Examples of devices are x-ray detectors, SERS sensors, THz emitters & detectors.
  • materials characterisation (optical spectroscopy, Raman mapping, AFM, SEM. XRD, XRR, electrical measurements)
