Background and activities
Kristine Bakken is a researcher in the FACET research group at the Department of Materials Science and engineering. Her research is focused on understanding the mechanisms governing the decomposition, pyrolysis and crystallization reactions taking place during thermal processing of ferroelectric oxide thin films from aqueous chemical solution deposition (CSD). A fundamental understanding of the mechanisms controlling the CSD fabrication are crucial in order to predict and tailor the properties of the resulting films and optimising the processing conditions. To observe this experimentally, in situ characterization tools has been developed and a protocol for data acquisition and processing established. In situ synchrotron X-ray diffraction (XRD) was used to study the crystallization and monitor the development of crystallographic texture and infrared spectroscopy was used to characterize the decomposition and identify the pyrolysis products.
The research is part of the Toppforsk project “From Aqueous Solutions to oxide Thin films and hierarchical Structures” (FASTS).
Kristine Bakken have a PhD in Materials Science and Engineering from NTNU (2020) and a master’s degree in Materials Science and Engineering from NTNU (2015). The title of the PhD thesis was “In situ Characterization of Ferroelectric Oxide Thin Films during Aqueous Chemical Solution Deposition” which was supervised by Mari-Ann Einarsrud, Tor Grande and Julia Glaum, the work was part of FASTS project. Her current research activities are a continuation of the PhD work. The title of her master’s thesis was titled: “Sintering of lead-free piezoelectric materials”, focused on the effect of the atmosphere during sintering on the properties of KNN-based (K0.5Na0.5NbO3-based) materials. A general broad background in Materials Science and engineering was established during her education at NTNU, with a specialization within synthesis, fabrication and characterization of inorganic ferroelectric ceramics.
