Magnetization Dynamics and Spinsupercurrents in Superconductingand Multiferroic Systems
(Doctoral thesis at NTNU;2016:5, Doctoral thesis, 2016)This thesis presents the research findings from three articles which have been published or submitted for publication. In the first article, we study the magnetization dynamics and anomalous supercurrent that can arise ... -
Chemical Vapour Deposition and Electron Microscopy Analysis of Graphene
(Master thesis, 2016)Graphene is a promising material for many applications, including electronics, energy technologies, chemical filters and mechanical materials. In this work, graphene has been grown by chemical vapour deposition (CVD) on ... -
New Calculation of Secondary Antiprotons in Cosmic Rays
(Peer reviewed; Journal article, 2016)A dramatic increase in the accuracy and statistics of space-borne cosmic ray (CR) measurements has yielded several breakthroughs over the last several years. The most puzzling is the rise in the positron fraction above 10 ... -
Spin caloritronics with superconductors: Enhanced thermoelectric effects, generalized Onsager response-matrix, and thermal spin currents
(Journal article, 2016)It has recently been proposed and experimentally demonstrated that it is possible to generate large thermoelectric effects in ferromagnet/superconductor structures due to a spin-dependent particle-hole asymmetry. Here, we ... -
Electron Microscopy Based Characterization of Semiconductor Nanowires
(Doctoral thesis at NTNU;2016:181, Doctoral thesis, 2016)One-dimensional semiconductor structures have attracted a large research interest, mainly for the purpose of novel or improved opto-electronic properties and applications. In this work, semiconductor nanowires grown using ... -
Formation of intermediate bands in silicon by transition metal doping - A DFT/DFTB computational study
(Master thesis, 2016)The intermediate band solar cell offers the possibility of increasing the efficiency of modern-day solar cells. By having a narrow intermediate band placed in the conventional band gap, sequential absorption of photons is ... -
Simulation of Two-Phase Flow in Porous Media using a Network Model.
(Master thesis, 2016)A network simulator has been used to study two-phase flow in porous media. The medium has been modeled as a bundle of tubes and the capillary forces inside these tubes have been investigated. This has been done by applying ... -
Electric-stress-induced Slip Lines in Jammed Particle Monolayers
(Journal article; Peer reviewed, 2016)Drops fully covered by particles, so called Pickering emulsion drops, are used to stabilize emulsions and are ideal templates for producing particles and advanced capsules. Recent studies show how electrohydrodynamic ... -
Solar and Lunar Tides in the MLT
(Master thesis, 2016)Simulations were done in Matlab to see how many days of data is needed to get accurate values of solar and lunar semidiurnal tides amplitudes and phases. For the component dominating the signal, 4 days can be sufficient, ... -
The impact of energetic electron precipitation on mesospheric hydroxyl during a year of solar minimum
(Journal article; Peer reviewed, 2016)In 2008 a sequence of geomagnetic storms occurred triggered by high-speed solar wind streams from coronal holes. Improved estimates of precipitating fluxes of energetic electrons are derived from measurements on board the ... -
Spectroscopic Ellipsometry of MoO3-x
(Master thesis, 2016)Intermediate band solar cells (IBSC) has a great potential to increase the efficiency of solar cells and reduce the costs of the generated electricity. To realize IBSC that contain one or more sub-band gap in the main band ... -
