Micro and Quantum Systems

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 currently looking for a new doctoral student to join our group. See the application and details of the open position here!
