Position

The Lab Manager of the micro- and nanotechnology laboratory at UiO (UiO MiNaLab), a node in the national infrastructure "The Norwegian Micro- and Nanofabrication Facility", NorFab. In addition, I have a researcher position at the semiconductor physics group at UiO, LENS.

Please get in touch if you would like to use our facilities.

Academic interests

Semiconductor materials for various applications, as ZnO-GaN alloys, II-IV nitrides and Ga₂O₃. Thin film processing employing sputtering (RF, HiPIMS and remote plasma sputtering) and structural, optical and electrical characterization.

Background

I started at the Materials, energy and nanotechnology (MENA) program at the University of Oslo in 2010. During my masters degree I also worked part-time at SINTEF Digital (MiNaLab). In april 2020 I defended my PhD thesis entitled "Functional properties and band gap engineering of (ZnO)_1-x(GaN)_x alloys.

Bachelor's degree: MENA UiO (2010-2013)
Master's degree: MENA UiO at the semiconductor physics group (2013-2015)
PhD: Semiconductor physics group at UiO (2016-2020)
