  Makkonen, Esko; Rossi, Tuomas P.; Larsen, Ask Hjorth; Lopez-Acevedo, Olga; Rinke, Patrick; Kuisma, Mikael; Chen, Xi (AIP Publishing, 2021)

  Electronic circular dichroism (ECD) is a powerful spectroscopy method for investigating chiral properties at the molecular level. ECD calculations with the commonly used linear-response time-dependent density functional ...

• Mechanical and optical properties of as-grown and thermally annealed titanium dioxide from titanium tetrachloride and water by atomic layer deposition 

  Ylivaara, Oili M.E.; Langner, Andreas; Liu, Xuwen; Schneider, Dieter; Julin, Jaakko; Arstila, Kai; Sintonen, Sakari; Ali, Saima; Lipsanen, Harri; Sajavaara, Timo; Hannula, Simo-Pekka; Puurunen, Riikka L. (Elsevier, 2021)

  The use of thin-films made by atomic layer deposition (ALD) is rapidly growing in the field of optical sensing. ALD TiO2 has been widely characterized for its physical and optical properties, but systematic information ...

• Charge Transfer Plasmons in Dimeric Electron Clusters 

  Selenius, Elli; Malola, Sami; Kuisma, Mikael; Häkkinen, Hannu (American Chemical Society, 2020)

  The tunability of the optical response of dimers of metal clusters and nanoparticles makes them ideal for many applications from sensing and imaging to inducing chemical reactions. We have studied charge transfer plasmons ...
