Micro and Quantum Systems

The Micro and Quantum Systems (MQS) group is located in Micronova, the nanofabrication facility of Aalto University. Our research interests span from nanoscale transport phenomena to quantum technologies and nanotechnology-based green energy production.

 Our current research topics include

-    Photoelectrocatalysis
-    Plasmonic nanoparticles
-    Nanoscale thermal engineering and thermoelectrics
-    Semiconductor quantum optics
-    Quantum information and -computing

We aim to combine simulation studies with experimental work to find intriguing approaches for experiments and concurrently, to validate the computational effort. In addition to research work, we participate actively in teaching, especially in the frameworks of Quantum Technologies B.Sc. program and Electronics and Nanotechnology M.Sc. program.

We are always interested in collaborating with new people. If you are interested in working with us, whether in terms of a M. Sc. thesis, or a research visit or -collaboration, please contact Prof. Ilkka Tittonen (contact details below).

We are hiring

PhD Student in Nanostructured Thermoelectrics (Link to the call and application instructions)

Research frameworks:

We are part of the Flagship on Photonics and Research Innovation (PREIN) programme managed by the Academy of Finland, as well as the Centre for Quantum Engineering (CQE) in Aalto University.

Current research frameworks:

  • The Academy of Finland project CarbonSurf, within the C1 Value program, for the development of novel CO2 catalysts and catalytic structures
  • The Academy of Finland project eVapor, within the ICT 2023 program, for the self-standing harvest of energy from water evaporation into electrical power for the operation of microcontrollers and other low-power devices

Past research frameworks:

  • The European Union project TransFlexTeg , within the H2020 program, for the development of large-area transparent thin films, their thermoelectric applications, and the investigation of thermal transport phenomena
  •  The Academy of Finland project OPTOBIO, within the New Energy Program, for the generation of solar fuels via photoelectrochemical water electrolysis by semiconductor and plasmonic materials
