Correlated Structural and Optical Characterisation of Individual AlGaN Nanowires on Graphene
(Master thesis, 2019)III-nitrider viser lovende egenskaper for bruk innen ultrafiolette optoelektroniske enheter, men en betydelig utfordring for fremtidig utbedring er lav effektivitet for enheter med kort bølgelengde. Med en økende etterspørsel ... -
Correlated subgrain and particle analysis of a recovered Al-Mn alloy by directly combining EBSD and backscatter electron imaging
(Journal article, 2022)Correlated analysis of (sub)grains and particles in alloys is important to understand transformation processes and control material properties. A multimodal data fusion workflow directly combining subgrain data from electron ... -
Correlated transmission electron microscopy and micro-photoluminescence studies of GaAs-based heterostructured semiconductor nanowires
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:319, Doctoral thesis, 2012)The focus of this work was to study the nanowire (NW) optical and structural properties on a single NW level. The GaAs-based heterostructured semiconductor NWs, grown by Au-assisted molecular beam epitaxy (MBE), were studied ... -
Correlating laser energy with compositional and atomic-level information of oxides in atom probe tomography
(Peer reviewed; Journal article, 2023)Atom probe tomography (APT) is a 3D analysis technique that offers unique chemical accuracy and sensitivity with sub-nanometer spatial resolution. There is an increasing interest in the application of APT to complex oxides ... -
Correlation between the mean wind in the mesosphere and lower thermosphere and solar cycles
(Master thesis, 2021)Middelvinden i den midtre atmosfæren transporterer kjemiske spesier som er sentrale for energibalansen i atmosfæren. Sterk avhengighet mellom de ulike lagene i atmosfæren gir motivasjon for å utforske middelvinden i ... -

Cosmic Ray Diffusion in the Hamiltonian Guiding Center Approximation
(Master thesis, 2019)Forå konstruere en metode tilå teste nøyaktigheten til den Hamiltonske føringssen- terapproksimasjonen undersøkes diffusjonskoeffisientene av kosmiske stråler propa- gert i et turbulent magnetisk felt. Målet er å reprodusere ... -
Cosmic ray models
(Journal article, 2019)We review progress in high-energy cosmic ray physics focusing on recent experimental results and models developed for their interpretation. Emphasis is put on the propagation of charged cosmic rays, covering the whole range ... -
Cosmic Rays from Pair-Instability Supernova Remnants
(Master thesis, 2015)Pair-instability supernovae are the most energetic thermonuclear explosions in the Universe, up to 100 times more energetic than type Ia supernovae. Around redshift z > 6 approximately one out of ten supernovae was a ... -
Cosmic-ray antinuclei as messengers of new physics: Status and outlook for the new decade
(Peer reviewed; Journal article, 2020)The precise measurement of cosmic-ray antinuclei serves as an important means for identifying the nature of dark matter and other new astrophysical phenomena, and could be used with other cosmic-ray species to understand ... -
Cost Optimality of Energy Systems in Zero Emission Buildings in Early Design Phase
(Master thesis, 2013)The building sector accounts for a significant proportion of industrial countries total energy use, thus a cut in this sector has been regarded necessary to reach future climate goals. An important measure in this context ... -
Coupling in the middle atmosphere related to the 2013 major sudden stratospheric warming
(Journal article; Peer reviewed, 2015)The previously reported observation of anomalous eastward gravity wave forcing at mesopause heights around the onset of the January 2013 major sudden stratospheric warming (SSW) over Trondheim, Norway (63° N, 10° E), is ... -
Covariant Quantum Electrodynamics in Terms of a Possible Ether Flow
(Theoretical Physics Seminar in Trondheim;4, Chapter, 1971)This paper from 1971 has a special history. At that time the present author was working with the covariant quantization procedure for an electromagnetic field in a dielectric medium. In such a theory, the commutator for ... -
