1. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER
2. Symmetry Analysis of Orbitals in a Plane Wave Basis : A Study on Molecules and Defects in Solids
Master-uppsats, Linköpings universitet/Teoretisk FysikSammanfattning : Modeling and analysing materials with theoretical tools is of great use when finding new systems for applications, for example, semiconductors with point defects can be used for quantum applications, like single photon emitters. One important aspect to consider symmetry, which can yield useful information about the properties of a system. LÄS MER
3. Birch leaf carbon dots: characterization and application in a light-emitting electrochemical cell
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : A new rising star in the carbon nanomaterial family is carbon dots. Carbon dots have received great attention due to their excellent luminescence and low toxicity. In this project, a new carbon dot derived from birch leaves is studied and characterized. LÄS MER
4. Material decomposition using a photon counting X-ray detector in low energy range
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. LÄS MER
5. Technical Lignin Characterization of Acacia crassicarpa and Eucalyptus Hybrids
Master-uppsats, KTH/Träkemi och massateknologiSammanfattning : Lignin är en av de vanligaste naturliga råvarorna på jorden och finns mestadels i trä. Nuförtiden är valoriseringen av lignin en av processutvecklingarna för teknologier inom massa- och pappersindustrin. Denna utveckling syftar till att öka värdet av lignin. LÄS MER
