Photoemission spectroscopies and their application in solid state and material physics
(Doctoral thesis at NTNU;2016:97, Doctoral thesis, 2016)Understanding the electronic properties of solid state systems is of fundamental importance to all matter. In particular, understanding and tailoring the properties of bound electrons in materials is an indispensable step ... -
Photoluminescence of InAs/Ga(N)As quantum dot intermediate band solar cells
(Master thesis, 2014)In this thesis InAs/Ga(N)As quantum dot intermediate band solar cells (QDIBSCs) are studied using photoluminescence (PL) spectroscopy. The samples in this thesis have been complete QD-IBSCs with doping in the substrate, the ... -
Photon-ALP oscillations at CTA energies
(Peer reviewed; Journal article, 2023)Axions and axion-like-particles (ALPs) are well motivated beyond the standard model particles that can explain a variety of unsolved problems in physics, such as the strong CP problem and the nature of dark matter. These ... -
Photon-ALP oscillations at TeV energies
(Peer reviewed; Journal article, 2022)Axion and axion-like-paricles (ALPs) are well motivated cold dark matter candidates. Nevertheless, an astoundingly huge parameter space remains unexplored despite much effort, ranging from fuzzy dark matter at ma∼10−22 eV ... -
Photon-ALP oscillations with ELMAG
(Peer reviewed; Journal article, 2022)ELMAG is a Monte Carlo program made to simulate electromagnetic cascades initiated by high-energy photons interacting with the extragalactic background light. Photons propagating in an external magnetic field may oscillate ... -
Photon-assisted Landau-Zener transitions in driven few-level systems
(Master thesis, 2019)I denne avhandlinga utforskar me Landau-Zener overgangar i drivne få-nivå system. Me behandlar drivingsfeltet både semi-klassisk (som ein tidsavhengig parameter i Hamilton operatoren) og heilt kvantemekanisk (som eit ... -
Photonic composite materials from cellulose nanorods and clay nanolayers
(Peer reviewed; Journal article, 2020)Cellulose nano crystals (CNCs) are promising materials for energy efficient buildings related to the control of reflectivity and heat absorption/reflection of light. In this sense it is important to improve CNCs films fire ... -
Photoprotection of riboflavin containing beverages
(Master thesis, 2012)Riboflavin, also known as vitamin B2 and one of the most easily absorbed nutrients,can be found in many different organisms. The most abundant source of riboflavin ismilk and dairy products; however it is also present in ... -
Photosensitizing effects of Al(III) Phthalocyanine Chloride Disulfonic Acid (AlPcS2a) – in vitro studies on AY-27 and T-24 cells
(Master thesis, 2021)Fotodynamisk terapi (PDT) er en behandlingsmetode som benytter et fotosensibiliserende stoff (PS) som induserer celledød ved aktivering av lys. Fotokjemisk internalisering (PCI) er en ny teknologi som bygger videre på de ... -
Photosensitizing Effects of Novel Glycosylated Chlorin Complexes on the AY-27 Cancer Cell Model
(Master thesis, 2020)Målet for dette prosjektet var å finne potensialet til KA20-familien av glykosylerte kloriner som fotosensibiliserende forbindelser i fotodynamisk terapi (PDT) av kreftsykdom. Kreft er en av verdens ledende dødsårsaker. ... -
