Optical Properties and Composition of Fe:ZnS Films
(Master thesis, 2014)Iron doped ZnS thin films were deposited using the physical vapor deposition technique over a concentration range of 0-12% Fe. The thickness and composition of the films were measured with a profilometer and EDS, respectively, ... -
Optical properties of biaxial nanopatterned gold plasmonic nanowired grid polarizer
(Journal article; Peer reviewed, 2013)Gold nanoparticles deposited on self-organized nano-ripple quartz substrates have been studied by spectroscopic Mueller matrix ellipsometry. The surface was found to have biaxial anisotropic optical properties. For electric ... -

(Master thesis, 2023)Denne oppgaven beskriver og demonstrerer en metode for å identifisere nye mellombåndsmaterialer for solceller ved å bruke tetthetsfunksjonalteori. Ca6FeN5 og varianter konstruert ved å erstatte Ca og N med henholdsvis Mg ... -
Optical Properties of Silicon Microwire Arrays for Photovoltaic Applications
(Master thesis, 2015)Silicon microwire-based solar cells represent a potential design strategy to reduce wafer related costs through reduced material usage and relaxed purity requirements. In this work we investigate the absorption of incident ... -
Optical properties of single diatom frustules revealed by confocal microspectroscopy
(Journal article; Peer reviewed, 2015)Optical properties of single diatom frustule valves from two different Coscinodiscus species (C. wailesii and C. centralis) are studied by transmission confocal hyperspectral imaging and numerical calculations. Light ... -
Optical Properties of truncated and coated spheroidal Nanoparticles on a Substrate
(Master thesis, 2012)In nanoparticle research it is common to perform optical measurements on particle films during deposition, to help understand the growth process. GranFilm is a software under development which can calculate the optical ... -
Optical resonators and metasurfaces modelled with multipole model
(Master thesis, 2021)I denne tesen ønsker vi å modelere den optiske responsen til en spesiell type gull nanopartikkel med smeltet silikat ved bruk av vektor sfærisk harmoniske funksjoner i Mie approksimasjonen og opptil kvadropol orden. Vi ... -
Optical response of rectangular array of elliptical plasmonic particles on glass revealed by Mueller matrix ellipsometry and finite element modeling
(Peer reviewed; Journal article, 2019)We report here on the optical response of elliptical gold particles arranged in a rectangular lattice on glass and probed at non-normal incidence in reflection using spectroscopic Mueller matrix ellipsometry in the energy ... -
Optical rotation from coupled cluster and density functional theories
(Doctoral theses at NTNU; 2018:31, Doctoral thesis, 2018)Chiral compounds are of fundamental importance in medical chemistry, biochemistry, and industry. Optical rotation, which is one of the most well-known optical responses of chiral molecules to an electromagnetic field, is ... -
Optical selection rules of zigzag graphene nanoribbons
(Journal article; Peer reviewed, 2017)We present an analytical tight-binding theory of the optical properties of graphene nanoribbons with zigzag edges. Applying the transfer matrix technique to the nearest-neighbor tight-binding Hamiltonian, we derive analytical ... -

Optimal boundary control of a contact thawing process for foodstuff
(Journal article, 2016)In this work an approach for thawing blocks of foodstuff, in particular fish, is introduced. The functional principle is based on plate freezer technology, which has been used in industry for decades. The aim of this work ... -
Optimal choice of state tomography quorum formed by projection operators
(Journal article; Peer reviewed, 2019)A minimal set of measurement operators for quantum state tomography has in the nondegenerate case ideally eigenbases which are mutually unbiased. This is different for the degenerate case. Here we consider the situation ... -
