Examining the three-dimensional structure of an AlGaAs shell on GaAs nanowires
(Master thesis, 2015)Semiconducting direct-bandgap nanowires (NWs) are a promising material system for future optoelectronic devices. In this work, the effect of shell growth temperature has been examined on the structural and optical properties ... -
Exceeding the Chandrasekhar-Clogston limit in flat-band superconductors: A multiband strong-coupling approach
(Peer reviewed; Journal article, 2023)Hybrid systems of superconductors and magnets display several intriguing properties, both from a fundamental physics point of view and with practical applications. Promising applications in superconducting spintronics ... -
Exceptional Microscale Plasticity in Amorphous Aluminum Oxide at Room Temperature
(Peer reviewed; Journal article, 2023)Oxide glasses are an elementary group of materials in modern society, but brittleness limits their wider usability at room temperature. As an exception to the rule, amorphous aluminum oxide (a-Al2O3) is a rare diatomic ... -
Exceptional points in oligomer chains
(Peer reviewed; Journal article, 2021)Symmetry underpins our understanding of physical law. Open systems, those in contact with their environment, can provide a platform to explore parity-time symmetry. While classical parity-time symmetric systems have received ... -
Exchange-enhanced ultrastrong magnon-magnon coupling in a compensated ferrimagnet
(Peer reviewed; Journal article, 2019)We experimentally study the spin dynamics in a gadolinium iron garnet single crystal using broadband ferromagnetic resonance. Close to the ferrimagnetic compensation temperature, we observe ultrastrong coupling of clockwise ... -
Exchange-only, nuclear spin-free qubits in semiconductor quantum dots
(Doctoral theses at NTNU;2020:255, Doctoral thesis, 2020)There are many successful proposals for using electron spins in quantum dots as qubits. However, a semiconductor quantum dot-based qubit that is scalable, reliable and robust enough for actual quantum information applications ... -
Excitation Spectrum and Superfluidity of Weakly Interacting, Spin-Orbit Coupled Bose-Einstein Condensate
(Master thesis, 2020)En svakt vekselvirkende, spinn-bane koblet, to-komponent, ultrakald Bose-gass bundet til et Bravais gitter blir studert. En analytisk framgangsmåte for å beskrive slike systemer i superfluid regimet blir presentert, motivert ... -
Exogenous lysophospholipids with large head groups perturb clathrin-mediated endocytosis
(Journal article; Peer reviewed, 2017)In this study, we have investigated how clathrin-dependent endocytosis is affected by exogenously added lysophospholipids (LPLs). Addition of LPLs with large head groups strongly inhibits transferrin (Tf ) endocytosis in ... -
Exotic Vortex Structures in Diffusive Superconducting Systems
(Master thesis, 2019)Selv vanligvis ikke-superledende materialer kan oppføre seg superledende dersom de blir plassert inntil en superleder. Dette fenometet kalles the proximity effect på engelsk, og når to materialer plasseres inntil hverandre ... -
Experimental and numerical studies of the scattering of light from a two-dimensional randomly rough interface in the presence of total internal reflection: Optical Yoneda peaks
(Journal article; Peer reviewed, 2016)The scattering of polarized light from a dielectric film sandwiched between two different semi-infinite dielectric media is studied experimentally and theoretically. The illuminated interface is planar, while the back ... -
Experimental Evaluation of Broadband Wave Propagation in Plates
(Master thesis, 2016)As the number of aging oil field in the North Sea is increasing, the number of plug and abandonment (P&A) jobs which has to be conducted on the wells going out of production, e.g. to prevent hydrocarbons from leaking out ... -
Experimental investigation of Gaussian random phase screen model for x-ray diffusers
(Journal article; Peer reviewed, 2019)The beam diffusing properties of stacked layers of diffuser material were evaluated experimentally and compared to a Gaussian random phase screen model. The model was found to give promising accuracy in combination with a ... -
