      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 ...
    • Modelling of the vertical deflection of ferroelectric bending tongues loaded at their free end 

      Cardoletti, Juliette; Radetinac, Aldin; Thiem, Daniel; Walker, Julian; Komissinskiy, Philipp; Xu, Bai-Xiang; Schlaak, Helmut; Trolier-Mckinstry, Susan E; Alff, Lambert (Peer reviewed; Journal article, 2019)
      In this work, a model to describe the vertical deflection of ferroelectric bending tongues with a load at their free end is proposed. The model is based on the ferroelectric switching criterion developed by Hwang et al. ...
