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 ...
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 ...
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 ...
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 ...
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 ...
Chemical Vapor Deposition of Cobalt-based Thin Films for Microelectronics
(2014-02-25)
In microelectronics, the device size continues to shrink to improve the performance and functionality, which sets technical challenges for the integrated circuit (IC) fabrication. Novel materials and processing techniques ...
Data Mining Chemistry and Crystal Structure
(2014-06-06)
The availability of large amounts of data generated by high-throughput computing and experimentation has generated interest in the application of machine learning techniques to materials science. Machine learning of materials ...
Developmentally-Inspired Engineering Of An Inductive Biomaterial for Odontogenesis
(2014-06-06)
Increasing demands for organ transplants and the depleting supply of available organs has heightened the need for alternatives to this growing problem. Tissue engineers strive to regenerate organs in the future; however ...
Novel Chemistries and Materials for Grid-Scale Energy Storage: Quinones and Halogen Catalysis
(2014-02-25)
In this work I describe various approaches to electrochemical energy storage at the grid-scale. Chapter 1 provides an introduction to energy storage and an overview of the history and development of flow batteries. Chapter ...
Plastic Behavior of Polycrytalline Thin Films: Discrete Dislocation Study
(2014-06-06)
Explaining the work-hardening behavior of crystalline materials and the size dependent plasticity has been a long lasting problem. Plastic deformation mainly arises from the collective motion of dislocations. Although ...
