Electron-Lattice Dynamics in pi-Conjugated Systems
Author(s) :
Hultell (Andersson), Magnus
Description :
In this thesis we explore in particular the dynamics of a special type of quasi-particle in pi-conjugated materials termed polaron, the origin of which is intimately related to the strong interactions between the electronic and the vibrational degrees of freedom within these systems. In order to con...

Studies of Charge Transport and Energy Level in Solar Cells Based on Polymer/Fullerene Bulk Heterojunction
Author(s) :
Gadisa, Abay
Description :
π-Conjugated polymers have attracted considerable attention since they are potential candidates for various opto-electronic devices such as solar cells, light emitting iodes, photodiodes, and transistors. Electronic de vices based on conjugated polymers can be easily processed at low temperature usi...

Modeling and OpenFOAM simulation of streamers in transformer oil Modellering och OpenFOAM-simulering av streamers i transformatorolja
Author(s) :
Fors, Jonathan
Description :
Electric breakdown in power transformers is preceded by pre-breakdown eventssuch as streamers. The understanding of these phenomena is important in orderto optimize liquid insulation systems. Earlier works have derived a model thatdescribes streamers in transformer oil and utilized a finite element ...

Biochip design based on tailored ethylene glycols
Author(s) :
Larsson, Andréas
Description :
Studies of biomolecular interactions are of interest for several reasons. Beside basic research, the knowledge gained from such studies is also very valuable in for example drug target identification. Medical care is another area where biomolecules may be used as biomarkers to aid physicians in maki...

Spectra and Dynamics of Excitattions in Long-Range Correlated Strucutures
Author(s) :
Kroon, Lars
Description :
Vad karaktäriserar en kristall? Svaret på denna till synes enkla fråga blir kanske att det är en anordning av atomer uppradade i periodiska mönster. Så ordnade strukturer kan studeras genom att det uppträder så kallade Braggtoppar i röntgendiffraktionsmönstret. Om frågan gäller elektrontäthetsfördel...

Growth and characterization of SiC and GaN
Author(s) :
Ciechonski, Rafal
Description :
At present, focus of the SiC crystal growth development is on improving the crystalline quality without polytype inclusions, micropipes and the occurrence of extended defects. The purity of the grown material, as well as intentional doping must be well controlled and the processes understood. High-q...

Molecular Quadratic Response Properties with Inclusion of Relativity
Author(s) :
Henriksson, Johan
Description :
This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms...

Effects of disorder in metallic systems from First-Principles calculations
Author(s) :
Asker, Christian
Description :
In this thesis, quantum-mechanical calculations within density-functional theory on metallic systems are presented. The overarching goal has been to investigate effects of disorder. In particular, one of the properties investigated is the bindingenergy shifts for core electrons in binary alloys usin...

Enligt fysiken eller enligt mig själv? : Gymnasieelever, fysiken och grundantaganden om världen
Author(s) :
Hansson, Lena
Description :
I avhandlingen studeras elevers grundantaganden om världen, samt de grundantaganden som eleverna förknippar med fysiken. Det är utifrån de grundantaganden vi gör om hur världen är beskaffad som vi försöker tolka och förstå nya fenomen och företeelser vi möter, t.ex. i den naturvetenskapliga undervis...

Growth of Pt/Mg Multilayer X-ray Mirrors : Effects of Sputter Yield Amplification Nil : Nil
Author(s) :
Sohail, Hafiz Muhammad
Description :
This thesis report is focused on the growth of Pt/Mg multilayers and the studies of the sputter yield amplification effect in these. The main application is to use the multilayers as X-ray mirrors reflecting an X-ray wavelength of 17 Å. This wavelength is important for astronomical applications in g...
