(Doctoral thesis / Doktoravhandling, 2011)Conventional silicon solar cells have a front-side contacted emitter. Back-contacted back-junction (BC-BJ) silicon solar cells, on the other hand, have both the complete metallization and the active diffused regions of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)This paper investigates the experiences of students in science, technology, engineering and mathematics (STEM) during their first year in higher education, based on 874 Danish and 1314 Norwegian students’ responses to an ...
-
(Master thesis / Masteroppgave, 2014)Zinc oxide is attractive for photovoltaic applications due to its properties as Transparent Conductive Oxide (TCO), as well as for rectifying heterojunctions to silicon. The present work investigates the electrical properties ...
-
(Doctoral thesis / Doktoravhandling, 2018)The band gap of semiconducting ZnO can be readily tuned through alloying it with other relevant oxides, such as CdO, consequently extending the performance of the corresponding materials and devices. In this context, one ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Recent progresses in nanoscale semiconductor technology have heightened the need for measurements of band gaps with high spatial resolution. Band gap mapping can be performed through a combination of probe-corrected scanning ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Introducing Cd into ZnO allows for bandgap engineering, potentially with particularly interesting properties to observe in compositionally graded samples. In this work, compositionally graded Zn1–xCdxO samples with ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)We show through experiments and supporting simulations that propagation of a highly relativistic and dense electron bunch through a plasma can lead to distributed injection of electrons, which depletes the accelerating ...
-
(Doctoral thesis / Doktoravhandling, 2019)The Advanced Wakefield Experiment (AWAKE) at CERN is the first plasma wakefield experiment to exploit the self-modulation instability in a long proton bunch in order to accelerate electrons to high energies. The first run ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)For the purpose of withstanding very high radiation doses, silicon pixel sensors with a ‘3D’ electrode geometry are being developed. Detectors of this kind are highly interesting for harch radiation environments such as ...
-
(Master thesis / Masteroppgave, 2017)Acoustic condition monitoring is an important technology for non-invasive condition monitoring, but using robust array signal processing techniques combined with machine learning is still not a fully explored field. This ...

-
(Master thesis / Masteroppgave, 2010)Både datamaskinen og det store mangfoldet av numeriske metoder for matematiske beregninger har gradvis utviklet seg som en følge av forskningsfrontens utømmelige spørsmålskilde og teknologiens tilsynelatende ustoppelige ...

-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We present an approach to bio-cementation of sand where the calcium source is prepared by dissolving powdered limestone (chalk) in lactic acid. Cementation is achieved through enzyme induced carbonate precipitation (EICP) ...
-
(Master thesis / Masteroppgave, 2015)The overall goal of this work has been to make bioactive surfaces with atomic layer deposition (ALD). To do this, a new ALD system with titanium tetraisopropoxide (TTIP) and lysine as precursors was developed with emphasis ...
