Decoherence and reservoir engineering in linear optical systems
(Turun yliopisto, 2023-06-02)
Realistic quantum systems interact with their environment and, as a consequence, may lose their quantum properties. This phenomenon is known as decoherence, and it keeps the many oddities of quantum mechanics at the level ...
Vortices and artificial defects in high-temperature superconducting thin films: Increasing the critical current densities via optimization of multilayer structures
(Turun yliopisto, 2023-06-29)
This dissertation studies the implications of vortex dynamics in high-temperature superconducting thin films. The combined use of both experimental and computational methods enabled one to draw otherwise unobtainable ...
Cantilever enhanced photoacoustic spectroscopy: The First two decades
(Turun yliopisto, 2024-02-29)
Two decades ago, the first experiments with a novel optical microphone using a small silicon cantilever as its sensing element were conducted at the University of Turku. In retrospect, those experiments revealed the potential ...
Studies of oxide-semiconductor and metal-semiconductor interfaces for reducing defect densities
(Turun yliopisto, 2024-01-26)
This thesis presents experimental studies of two fundamental components of electronic devices: an oxide- and metal-semiconductor interface. The importance of these interfaces increases continuously when a device size is ...
Galaxy evolution through the lens of active galactic nuclei, their host galaxies, and environments
(Turun yliopisto, 2024-06-11)
The body of research relayed in this dissertation pertains to investigating the immediate environments of Type I quasars for clues to the formation and evolution of galaxies through observations. The neighboring galaxies ...
Structural and chemical modifications of porous silicon for biomedical applications
(Turun yliopisto, 2024-06-01)
The versatility in properties of porous silicon (PSi) has enabled a broad spectrum of applications, ranging from microelectronics and various types of sensors to its use as a biocompatible material in drug delivery.
