Proximity-Induced Superconductivity in CdTe-HgTe Core-Shell Nanowires
(Journal article; Peer reviewed, 2019)In this Letter we report on proximity superconductivity induced in CdTe–HgTe core–shell nanowires, a quasi-one-dimensional heterostructure of the topological insulator HgTe. We demonstrate a Josephson supercurrent in our ... -
Pseudo-T2 mapping for normalization of T2-weighted prostate MRI
(Peer reviewed; Journal article, 2022)Objective Signal intensity normalization is necessary to reduce heterogeneity in T2-weighted (T2W) magnetic resonance imaging (MRI) for quantitative analysis of multicenter data. AutoRef is an automated dual-reference ... -
Psychometric properties of the person-centred coordinated care experience questionnaire (P3CEQ) in a Norwegian radiotherapy setting
(Peer reviewed; Journal article, 2022)The number of older adults with cancer is increasing. Radiotherapy is an important treatment modality for cancer and may cause side effects and distress. Patient-reported experience measures aim to measure patients’ ... -
Psychophysics of reading and illumination needs during reading in visually impaired subjects with age-related macular degeneration
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:32, Doctoral thesis, 2005)The primary aim of this study was to contribute to a better understanding of how we can optimize reading conditions for subjects with age-related macular degeneration (AMD). In order to achieve this goal, we have developed ... -
Pulsed laser ablation and deposition of ZnS:Cr
(Journal article; Peer reviewed, 2015)We present a method to deposit films with a range of doping concentrations/dilute alloys, from a single target in pulsed laser deposition (PLD). Cr-doped ZnS films were deposited by ablating a target consisting Cr particles ... -
Pulsed Laser Deposited TiO2: X-Ray Diffraction and Raman Spectroscopy Studies
(Master thesis, 2022)Pulserende laserdeponerte TiO2-tynnfilmer har blitt undersøkt ved røntgen-diffraksjon (XRD) og ramanspektroskopi. Utvalget av TiO2-tynnfilmer bestod av både udopede og (Cr,N)-dopede filmer. Bakgrunnen for studien var å ... -
Pulsed Laser Deposition of Zinc Sulfide Thin Films on Silicon: The influence of substrate orientation and preparation on thin film morphology and texture
(Master thesis, 2014)The effect of orientation and preparation of silicon substrates on the growth morphology and crystalline structure of ZnS thin films deposited by pulsed laser deposition (PLD) has been investigated through scanning electron ... -
Pump-probe experiments of multicrystalline silicon for solar cell applications
(Master thesis, 2012)In order to make cost effective solar cells from mc-Si materials, the negative contributions from defects and impurities should be reduced. The analysis of the photogenerated carrier properties is therefore of great ... -
Pure spin current generated by reflection at a normal metal/two-dimensional electron gas interface
(Journal article; Peer reviewed, 2010)The concept of a spin current is a useful tool in understanding spin transport in hybrid systems but its very definition is problematic in systems where spin-orbit coupling effects are strong. In the absence of spin-dependent ... -
QCD at finite isospin density: chiral perturbation theory confronts lattice data
(Peer reviewed; Journal article, 2020)We consider the thermodynamics of three-flavor QCD in the pion-condensed phase at nonzero isospin chemical potential (μI) and vanishing temperature using chiral perturbation theory in the isospin limit. The transition from ... -
QCD phase diagram in a constant magnetic background: Inverse magnetic catalysis: where models meet the lattice
(Peer reviewed; Journal article, 2021)Magnetic catalysis is the enhancement of a condensate due to the presence of an external magnetic field. Magnetic catalysis at T=0 is a robust phenomenon in low-energy theories and models of QCD as well as in lattice ... -
A qualitative study on how to scaffold for collaborative learning in an innovative learning area, a student perspective

Quantification and Qualitative Effects of Different PEGylations on Poly(butyl cyanoacrylate) Nanoparticles
(Journal article, 2017)Protein adsorption on nanoparticles (NPs) used in nanomedicine leads to opsonization and activation of the complement system in blood, which substantially reduces the blood circulation time of NPs. The most commonly used ... -
Quantification of Blood Flow in Cerebral Arteries at 7T MR
(Master thesis, 2022)Avbildning med 2D fasekontrast gjør det mulig å kvantifisere blodgjennomstrømning (mL/min) i cerebrale blodårer, og kan være et nyttig verktøy for å planlegge behandling og undersøke langtidseffekter hos pasienter med ... -
Quantifying the hydroxyapatite orientation near the ossification front in a piglet femoral condyle using X-ray diffraction tensor tomography
(Peer reviewed; Journal article, 2021)While a detailed knowledge of the hierarchical structure and morphology of the extracellular matrix is considered crucial for understanding the physiological and mechanical properties of bone and cartilage, the orientation ... -
Quantifying the influence of the stratosphere on the mesosphere and lower thermasphere
(Doctoral thesis at NTNU;2015:22, Doctoral thesis, 2015)In this thesis, the influence of the major modes of stratospheric variability - the seasonal cycle and sudden stratospheric warmings (SSWs) in the extratropics, and the quasi-biennial oscillation (QBO) in the equatorial ... -
Quantitative (S)TEM analysis of intermediate band solar cell materials
(Master thesis, 2011)In this thesis the strain properties of two InAs/GaAs quantum dot intermediate band solar cell materials have been explored. Both samples were thin films grown on a (100) GaAs substrate. The quantum dot material was InAs, ... -
Quantitative 3-D colocalization analysis as a tool to study the intracellular trafficking and dissociation of pDNA-chitosan polyplexes
