(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)The role of vacancy clustering and acceptor activation on resistivity evolution in N ion-implanted n-type hydrothermally grown bulk ZnO has been investigated by positron annihilation spectroscopy, resistivity measurements, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)We have used depth-resolved cathodoluminescence, positron annihilation, and surface photovoltage spectroscopies to determine the energy levels of Zn vacancies and vacancy clusters in bulk ZnO crystals. Doppler broadening-measured ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1999)A mixed-valence state, formally denoted as Fe 2 . 5 + , is observed in the 300 K Mössbauer spectra of the most reduced samples of SmBaFe 2 O 5 + w . Upon cooling below the Verwey-type transition temperature (TV≈ 200 K ) ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background One important physiological response to environmental stress in animals is change in gene expression. To obtain reliable data from gene expression studies using RT-qPCR it is important to evaluate ...
-
(Master thesis / Masteroppgave, 2017)This thesis deals with the validation of the NGU susceptibility map for debris slides/avalanches and small to medium sized debris flows. The susceptibility model developed by NGU is a nation-wide model, predicting source ...
