11. Electronic Structure and Transport Properties of Carbon Based Materials
Sammanfattning : In the past decade the interest in molecular electronic devices has escalated. The synthesis of molecular crystals has improved, providing single crystals or thin films with mobility comparable with or even higher than amorphous silicon. Their mechanical flexibility admits new types of applications and usage of electronic devices. LÄS MER
12. Monte Carlo Studies of Charge Transport Below the Mobility Edge
Sammanfattning : Charge transport below the mobility edge, where the charge carriers are hopping between localized electronic states, is the dominant charge transport mechanism in a wide range of disordered materials. This type of incoherent charge transport is fundamentally different from the coherent charge transport in ordered crystalline materials. LÄS MER
13. A Theoretical Study of Charge Transport in Molecular Crystals
Sammanfattning : The main objective of this thesis is to provide a deeper understanding of the charge transport phenomena occuring in molecular crystals. The focus is on the stability and the dynamics of the polaron as the charge carrier.To achieve this goal, a series of numerical calculations are performed using the semi-emprical "Holstien-Peierls" model.

14. Statistical Feature Selection : With Applications in Life Science
Sammanfattning : The sequencing of the human genome has changed life science research in many ways. Novel measurement technologies such as microarray expression analysis, genome-wide SNP typing and mass spectrometry are now producing experimental data of extremely high dimensions. LÄS MER
15. Light interactions in flexible conjugated dyes
Sammanfattning : In this thesis methodological developments have been made for the description of flexible conjugated dyes in room temperature spectrum calculations.The methods in question target increased accuracy and efficiency by combining classical molecular dynamics (MD) simulations with time-dependent response theory spectrum calculations.
