• Detecting minute amounts of nitrogen in GaNAs thin films using STEM and CBED 

      Vatanparast, Maryam; Shao, Yu-Tsun; Rajpalke, Mohana; Fimland, Bjørn-Ove; Reenaas, Turid Dory; Holmestad, Randi; Vullum, Per Erik; Zuo, Jian Min (Journal article; Peer reviewed, 2021)
      Nitrogen (N) is a common element added to GaAs for band gap engineering and strain compensation. However, detection of small amounts of N is difficult for electron microscopy as well as for other chemical analysis techniques. ...
    • Laser-induced spatial composition gradients in SiGe core fiber 

      Wu, Wei (Doctoral theses at NTNU;2020:219, Doctoral thesis, 2020)
      An important contributor to global warming is greenhouse gas emission caused by burning fuels such as oil and coal. To preserve the environment for the whole world and to simultaneously meet growing global energy demand, ...
    • Tailoring properties of nanostructured MoO3−x thin films by aqueous solution deposition 

      Inzani, Katherine; Nematollahi, Mohammadreza; Selbach, Sverre Magnus; Grande, Tor; Waalekalv, Magnus Langøien; Brakstad, Thomas; Reenaas, Turid Dory; Kildemo, Morten; Vullum-Bruer, Fride (Journal article, 2018)
      Molybdenum oxide films are required for a large range of optical, electronic and catalytic applications, and optimal film characteristics are similarly broad. Furthermore, the layered crystal structure of MoO3 is suited ...
