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 ...
Performance and reliability of PZT-based piezoelectric micromirrors operated in realistic environments

Dahl-Hansen, Runar Plunnecke; Tyholdt, Frode; Tybell, Per Thomas Martin (Chapter, 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 ...
