Backscattering in helical edge states from a magnetic impurity and Rashba disorder
(Journal article; Peer reviewed, 2016)Transport by helical edge states of a quantum spin Hall insulator is experimentally characterized by a weakly temperature-dependent mean free path of a few microns and by reproducible conductance oscillations, challenging ... -
Backward magnetostatic surface spin waves in coupled Co/FeNi bilayers
(Peer reviewed; Journal article, 2020)Spin waves (SWs) in coupled Co/FeNi bilayers are probed by the Brillouin light‐scattering technique. Two types of SWs, magnetostatic surface spin waves (MSSWs) and perpendicular standing SWs, are identified. The dispersion ... -
Bacterial Microarrays by Microcontact Printing: Development of a Method for Immobilizing Live Bacteria on Microarrays
(Master thesis, 2014)Traditional microbiological experimental methods generally reveal population-wide statistics and are not capable of revealing variations between individual cells. In an effort to address this, a cheap, quick and easy means ... -
Band gaps in jagged and straight graphene nanoribbons tunable by an external electric field
(Journal article; Peer reviewed, 2015)Band gap control by an external field is useful in various optical, infrared and THz applications. However, widely tunable band gaps are still not practical due to a variety of reasons. Using the orthogonal tight-binding ... -
Band-edge modification and mid-infrared absorption of co-deposited FexZn1-xS thin films
(Journal article; Peer reviewed, 2015)The bandgap of iron-doped ZnS has been reported by others to change significantly under the addition of a few atomic percent of iron, which would have significant implications for solar energy. Here, thin films of FexZn1-xS ... -
Bandgap measurement of high refractive index materials by off-axis EELS
(Journal article; Peer reviewed, 2017)In the present work Cs aberration corrected and monochromated scanning transmission electron microscopy electron energy loss spectroscopy (STEM-EELS) has been used to explore experimental set-ups that allow bandgaps of ... -
Bandgap optimization for colored multi-bandgap solar cells
(Master thesis, 2024)Denne masteroppgaven ser på den teoretiske virkningsgraden for fargede solceller. Dette har blitt gjort tidligere for ideelle tilfeller, men i denne masteroppgaven vill mer realistiske beregninger bli gjort. Beregningene ... -
Behaviour of the S1 and S2 Components of the Semidiurnal Tide in the MLT
(Master thesis, 2016)9 years (2000-2008) of wind data from a longitudinal chain of up to 10 Super Dual Auroral Radar Network (SuperDARN) radars spanning over 184 degrees in longitude and ranging in latitude from 51.4 - 65.7 degrees N is used ... -
Benchmarking microbarom radiation and propagation model against infrasound recordings: a vespagram-based approach
(Journal article; Peer reviewed, 2021)This study investigates the use of a vespagram-based approach as a tool for multi-directional comparison between simulated microbarom soundscapes and infrasound data recorded at ground-based array stations. Data recorded ... -
Beregninger med sikte på et DFT-basert reaktivt kraftfelt for strontium, bly, titan og oksygen.
(Master thesis, 2009)Denne oppgaven tar utgangspunkt i et prosjekt som hadde til hensikt å studere groing av en PbTiO3-perovskittfilm på kubisk SrTiO3, hvor bruksområdene for dette inkluderer minnehåndtering i databrikker og lignende. Denne ... -
Beregningsorientering i fysikkutdanning
(Master thesis, 2022)Realfagsutdanningen blir i større og større grad påvirket av teknologisk utvikling for å tilpasse seg arbeidslivets behov. Moderne teknologi gir mulighet for folk flest til å gjøre enorme beregninger, og det er av stor ... -
Betti designature and elastic demultiple of multi-component seismic data
(Doktoravhandlinger ved NTNU, 1503-8181, Doctoral thesis, 2003)In this work I show that Bettis's theorem provides the theoretical basis for eliminating the physical response of the medium above the receiver surface (overburden) in the multi-component source, multi-component receiver ... -
Beyond the Chandrasekhar-Clogston limit in a spin-split superconductor driven out of equilibrium by a spin-accumulation
(Master thesis, 2023)En spinn-splittet superledende film koblet til normalmetall-reservoarer drevet ut av likevekt av en spinnavhengig spenning blir undersøkt numerisk ved å løse den kvasiklassiske Usadelligningen. To ulike oppsett blir ... -
Bio-instructive materials for musculoskeletal regeneration
(Journal article; Peer reviewed, 2019)The prevalence and cost of disorders affecting the musculoskeletal system are predicted to rise significantly in the coming years due to the aging global population and the increase of associated risk factors. Despite being ... -
Biochemical and Structural Characterization of Neocartilage Formed by Mesenchymal Stem Cells in Alginate Hydrogels
(Journal article; Peer reviewed, 2014)A popular approach to make neocartilage in vitro is to immobilize cells with chondrogenic potential in hydrogels. However, functional cartilage cannot be obtained by control of cells only, as function of cartilage is largely ... -
