Ongoing effects of pandemic-imposed learning disruption on student attitudes
Teemu Hynninen, Henna Pesonen, Olli Lintu +1
We present a study on the development of Finnish first-year physics majors' attitudes towards physics, as measured by the Colorado Learning Attitudes about Science Survey, before,…
First-principles investigations of the magnetic phase diagram of GdCaMnO
Hichem Ben Hamed, Martin Hoffmann, Waheed A. Adeagbo +5
We studied for the first time the magnetic phase diagram of the rare-earth manganites series GdCaMnO (GCMO) over the full concentration range based on density f…
Adsorption of metal impurities on H-terminated Si surfaces and their influence on the wet chemical etching of Si
Teemu Hynninen, Adam S Foster, Miguel A Gosalvez +2
We use first-principles methods to investigate the adsorption of Cu, Pb, Ag, and Mg onto a H-terminated Si surface. We show that Cu and Pb can adsorb strongly while Ag and Mg are f…
High Curie temperatures in (Ga,Mn)N from Mn clustering
Teemu Hynninen, Hannes Raebiger, Andres Ayuela +1
The effect of microscopic Mn cluster distribution on the Curie temperature (Tc) is studied using density-functional calculations. We find that the calculated Tc depends crucially o…
