1. Magnetoplasmonic nanostructures
Sammanfattning : Surfaces that are nanopatterned, metallic, and magnetic can support surface plasmon resonances, providing an alternative and effective way to reconfigure flat optical components. Utilising a range of near- and far-field characterisation techniques, the optical and magneto-optical properties of lithographically patterned thin magnetic films are investigated. LÄS MER
2. Semiconductor Hetero- and Nanostructures
Sammanfattning : In this thesis, chemical beam epitaxy was used to fabricate nm-sized crystalline structures. Most of the systems were based on heterostructures, i.e., combinations of different kinds of crystalline materials. LÄS MER
3. Numerical Simulations of Plasmonic Nanostructures
Sammanfattning : This thesis focuses on the study of metallic nanostructures that support plasmons. Special emphasis is devoted to two specific numerical methods that allow us to predict plasmon characteristics: the discrete dipole approximation (DDA) and the Green's tensor (GT) method. LÄS MER
4. Electronic structure and transport in exotic nanostructures
Sammanfattning : This thesis explores the physics of nanostructures involving nanowires, quantum dots, superconductors, and topological insulators. These systems serve as excellent platforms for fundamental physics studies and quantum technology applications. LÄS MER
5. Synthesis, Characterization and Applications of Metal Oxide Nanostructures
Sammanfattning : The main objective of nanotechnology is to build self-powered nanosystems that are ultrasmall in size, exhibit super sensitivity, extraordinary multi functionality, and extremely low power consumption. As we all know that 21st century has brought two most important challenges for us. One is energy shortage and the other is global warming. LÄS MER
