Structure and Thermoelectric Properties of ZnO Based Materials
(2013-10-18)
The present dissertation investigates the relationship between the structure and thermoelectric properties of ZnO based materials, with a focus on trivalent element doping on engineering the microstructure and altering the ...
Defects in Hard-Sphere Colloidal Crystals
(2013-03-15)
Colloidal crystals of \(1.55 \mu m\) diameter silica particles were grown on {100} and flat templates by sedimentation and centrifugation. The particles interact as hard spheres. The vacancies and divacancies in these ...
First-Principles Multiscale Investigation of Structural and Chemical Defects in Metals
(2013-03-08)
This thesis explores multiscale approaches to describe structural and chemical defects in metals. Particular emphasis is placed on investigating processes involving grain boundaries (GBs) in combination with impurity and ...
Cooperativity, Fluctuations and Inhomogeneities in Soft Matter
(2013-09-30)
This thesis presents four investigations into mechanical aspects of soft thin structures, focusing on the effects of stochastic and thermal fluctuations and of material inhomogeneities. First, we study the self-organization ...
Aqueous Solution Synthesis of ZnO for Application in Optoelectronics
(2013-09-23)
Recently, ZnO has garnered widespread attention in the semiconductor community for its large set of useful properties, which include a wide bandgap and its resulting optical transparency, a large exciton binding energy, a ...
