Electrochemically driven degradation of chemical solution deposited ferroelectric thin-films in humid ambient
Dahl-Hansen, Runar Plunnecke; Polfus, Jonathan Marc; Vøllestad, Einar; Akkopru-Akgun, Betul; Denis, Lyndsey; Coleman, Kathleen; Tyholdt, Frode; Trolier-Mckinstry, Susan E; Tybell, Per Thomas Martin (Peer reviewed; Journal article, 2020)The ambient humidity significantly accelerates the degradation of lead zirconate titanate (PZT) films in microelectromechanical systems; the cause of such degradation is under debate. Here, it is shown that the degradation ... -
Growth and Strain Relations in (001)-oriented Ferroelectric and Ferromagnetic Perovskite Oxide Thin Films
Dahl-Hansen, Runar Plunnecke (Master thesis, 2013)The wide range of properties offered by perovskite oxides demands high quality thin films and growth control on several interfaces. In this work, growth of ferroelectric BaTiO3 (BTO) on (001)-oriented SrTiO3 (STO) and ... -
On the effect of water-induced degradation of thin-film piezoelectric microelectromechanical systems
Dahl-Hansen, Runar Plunnecke; Tyholdt, Frode; Gjessing, Jo; Vogl, Andreas; Wittendorp, Paul; Vedum, Jon; Tybell, Per Thomas Martin (Peer reviewed; Journal article, 2021)Lifetime and reliability in realistic operating conditions are important parameters for the application of thin-film piezoelectric microelectromechanical systems (piezoMEMS) based on lead zirconate titanate (PZT). Humidity ... -
Performance and reliability of PZT-based piezoelectric micromirrors operated in realistic environments
Dahl-Hansen, Runar Plunnecke; Tyholdt, Frode; Tybell, Per Thomas Martin (Journal article; Peer reviewed, 2018)The number of application areas for piezoelectric micro electromechanical systems based on PZT have increased rapidly over the years. Thus, to continue the development towards commercial deployment, characterizing lifetime ... -
