6. Charge and Spin Transport in Parallel-Coupled Quantum Dots in Nanowires
Abstract : This thesis explores crystal-phase engineering of nanowires to fabricate advanced quantum structures for charge and spin transport studies. Quantum dots formed by crystal-phase tuning during epitaxial growth of InAs nanowires were used as a starting point to realize and electrically characterize two different types of parallel-coupled quantum dots; electron-hole quantum dots and electron-electron quantum dots.

7. Thermally and Optically Excited Electron Transport in Semiconductor Nanowires
Abstract : This thesis explores the transport of thermally and optically excited electrons invarious nanowire structures. On one hand, electrons are thermally excited when thetemperature is nonzero, and the thermal energy help them surmount energy barriersthat are present in the material. READ MORE

8. Doping of Semiconductor Nanowires
Abstract : In this thesis, in situ doping during growth of III-V semiconductor nanowires, primarily for photovoltaic applications, is investigated. The nanowires were grown by metalorganic vapor phase epitaxy (MOVPE), with gold seed particles. READ MORE

9. Synchrotron light based spectroscopy of MBE-grown (GaMn)As structures
Abstract : Structures based on the diluted magnetic semiconductor (GaMn)As have been grown by low temperature molecular beam epitaxy and studied using synchrotron radiation based electron spectroscopy. An investigation of modifications due to in situ low temperature annealing under amorphous As capping has been performed. READ MORE

10. Aberration-Corrected Analytical Electron Microscopy of Transition Metal Nitride and Silicon Nitride Multilayers
Abstract : Two multilayer thin films have been studied: TiN/SiNx and ZrN/SiNx. A double-corrected transmission electron microscope (TEM) was utilized for imaging and spectroscopy. Imaging was carried out in scanning mode (STEM) for all samples. READ MORE
