Natural Dyes as Candidate Materials for Organic Solar Cells - An Optical, Electronic and Structural Characterisation
(Master thesis, 2018)Natural dyes strongly absorbing light in the visible spectrum are appealing ma- terials for the use in organic solar cells, due to their direct availability from nature. An especially interesting potential application ... -
Naturvitenskapens egenart som en del av fysikkundervisningen
(Master thesis, 2023)Vitenskap har i århundrer vært med å prege samfunnet som vi lever i. Hva det er som kjennetegner vitenskap blir ofte kalt for naturvitenskapens egenart. I et samfunn i stadig raskere utvikling, hvor tilgangen på informasjon ... -
Theoretical studies of the intermidiate band solar cell
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:94, Doctoral thesis, 2010)This thesis presents theoretical work on the intermediate band solar cell (IBCS). It is divided into two main parts: The first part is an introduction to basic solar cell physics and a presentation of central parts of the ... -
Net optical parametric gain in a submicron silicon core fiber pumped in the telecom band
(Peer reviewed; Journal article, 2019)A silicon core fiber (SCF) has been designed and fabricated with a dispersion engineered profile to support broadband optical parametric amplification across the telecom window. The combination of low optical transmission ... -
Network topology of the desert rose
(Journal article; Peer reviewed, 2015-09-08)Desert roses are gypsum crystals that consist of intersecting disks. We determine their geometrical structure using computer assisted tomography. By mapping the geometrical structure onto a graph, the topology of the desert ... -
Neuromorphic computing with ferromagnetic nano-oscillators
(Master thesis, 2023)I løpet av de siste ̊arene har nevrale nettverk blitt fremtredende gjennom maskin- læring. Disse er ofte implementert p ̊a kommersielt tilgjengelige, transistorbaserte enheter, som ikke er godt egnet til ̊a etterligne ... -
A Neutral Beam Model for High-Energy Neutrino Emission from the Blazar TXS 0506+056
(Peer reviewed; Journal article, 2020)The IceCube collaboration reported an ~3.5σ excess of 13 ± 5 neutrino events in the direction of the blazar TXS 0506+056 during an ~6 month period in 2014–2015, as well as the (~3σ) detection of a high-energy muon neutrino ... -
Neutron and Quark Stars
(Master thesis, 2020)I denne masteroppgaven tar vi for oss mange av hovedtrekkene knyttet til det å bestemme strukturen og den øvre massegrensen til kompakte stjerner, spesielt nøytronstjerner og kvarkstjerner. Vi begynner med en innføring i ... -
The Neutron Star Population in M28: A Joint Chandra/GBT Look at Pulsar Paradise
(Peer reviewed; Journal article, 2022)We present the results of a deep study of the neutron star (NS) population in the globular cluster M28 (NGC 6626), using the full 330 ks 2002–2015 ACIS data set from the Chandra X-ray Observatory and coordinated radio ... -
Neutron stars - Investigating candidates for the equation of state in the relativistic mean-field approximation
(Master thesis, 2018)Various models for the equation of state (EoS) for a neutron star have been considered using the relativistic mean-field approximation. Firstly, we derive Einstein's field equations and apply them to a spherically symmetric ... -
Neutron Stars - Study of the Mass-Radius Relation and Mean-Field Approaches to the Equation of State
(Master thesis, 2017)The structure and the relation between the total mass, the radius and the central energy density of a neutron star may be found by numerically solving a set of three coupled differential equations. One of these equations ... -
Neutron Stars: The electromagnetic forces at the surface and its implications.
(Master thesis, 2013)A neutron star is a compact object formed in a core-collapse supernova explosion or in an accretion process of a white dwarf. Its radius is of the order of tens of kilometers and its mass on the order of one solar mass. ... -
"Never at Rest" - Anvendelse av kraftbegrepet i lærebøker i fysikk for videregående skole
(Master thesis, 2014)Denne oppgaven har undersøkt hvordan kraft behandles i lærebøker i fysikk beregnet på elever i den videregående skolen i Norge. Læreverkene <> og <> for Fysikk 1 og Fysikk 2, i alt fire bøker, har dannet grunnlaget for ... -
“Never at rest”: developing a conceptual framework for descriptions of ‘force’ in physics textbooks
(Peer reviewed; Journal article, 2020)The concept of ‘force’ is abstract and challenging for many physics students, and many studies have revealed misconceptions that hinder students’ understanding and learning in classical physics. One reason for this may be ... -
