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 ... -
High-quality dense 3D point clouds with active stereo and a miniaturizable interferometric pattern projector
Thorstensen, Jostein Bruun; Thielemann, Jens T; Risholm, Petter; Gjessing, Jo; Dahl-Hansen, Runar Plunnecke; Tschudi, Jon (Peer reviewed; Journal article, 2021)We have built and characterized a compact, simple and flexible 3D camera based on interferometric fringe projection and stereo reconstruction. The camera uses multi-frame active stereo as basis for 3D reconstruction, ... -
High-Rate Epitaxial Growth of Silicon Using Electron Beam Evaporation at High Temperatures
Stange, Marit Synnøve Sæverud; Sunde, Tor Olav Løveng; Dahl-Hansen, Runar Plunnecke; Rajput, Kalpna; Graff, Joachim Seland; Belle, Branson Delano; Ulyashin, Alexander (Peer reviewed; Journal article, 2023)This paper describes the high-rate (~1.5 μm/min) growth of Si films on Si supporting substrates with (100) crystallographic orientation at 600 °C, 800 °C, and 1000 °C in a vacuum environment of ~1 × 10−5 mbar using electron ... -
On the Evolution of Stress and Microstructure in Radio Frequency-Sputtered Lead-Free (Ba,Ca)(Zr,Ti)O3 Thin Films
Dahl-Hansen, Runar Plunnecke; Stange, Marit Synnøve Sæverud; Sunde, Tor Olav Løveng; Ræder, Johan Henrik; Rørvik, Per Martin Ljønes (Peer reviewed; Journal article, 2024)Thin-film piezoelectrics are widely investigated for actuators and energy harvesters, but there are few alternatives to toxic lead zirconate titanate. Biocompatible Ca- and Zr-modified BaTiO3 (BCZT) is one of the most ...
