The Centre of Excellence in Computational Nanoscience consisted of six research groups based at the Helsinki University of Technology Physics Laboratory. Specialising in theoretical and computational research on nanoscience materials, structures and components, the CoE's major research interests included the electronic properties of materials and nanostructures, the quantum physics of multiple-particle phenomena, and the nanostructures of surfaces and interfaces.
Research at the CoE was broadly based and covered phenomena that varied in size from the atom level to the macro world. As well as engaging in research, the CoE produced various practical applications. The CoE was a Centre of Excellence in Research nominated by the Academy of Finland also during the 2000–2005 period.
The Coe was headed by Academy Professor Risto Nieminen.
