Advanced Transmission Electron Microscopy of III-V Nanowires
Nilsen, Julie Stene (Doctoral theses at NTNU;2020:84, Doctoral thesis, 2020)Semiconducting nanowires have many interesting applications and a promising future as building blocks for optoelectronic devices. In this work, the aim is to improve the characterization of the nanowire structure and ... -
Growth study of self-assembled GaN nanocolumns on silica glass by plasma assisted molecular beam epitaxy
Liudi Mulyo, Andreas; Konno, Yuta; Nilsen, Julie Stene; Van Helvoort, Antonius; Fimland, Bjørn-Ove; Weman, Helge; Kishino, Katsumi (Journal article; Peer reviewed, 2017)We demonstrate GaN nanocolumn growth on fused silica glass by plasma-assisted molecular beam epitaxy. The effect of the substrate temperature, Ga flux and N2 flow rate on the structural and optical properties are studied. ... -
Position controlled Growth of GaAs/AlGaAs core-shell Nanowires - more uniform in their structural and optical Properties?
Nilsen, Julie Stene (Master thesis, 2014)Semiconducting nanowires (NWs), especially those with a direct band gap, could be promising building blocks in future optoelectronic devices. Position controlled, self catalyzed GaAs/AlGaAs core-shell NWs with an AlGaAs ... -
