1. Baseband Processing for 5G and Beyond: Algorithms, VLSI Architectures, and Co-design
Sammanfattning : In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities.

2. Ferroelectric Na0.5K0.5NbO3 as an electro-optic material
Sammanfattning : Ferroelectrics are a group of advanced electronic materialswith a wide variety of properties useful in applications suchas memory devices, resonators and filters, infrared sensors,microelectromechanical systems, and optical waveguides andmodulators. Among the oxide perovskite-structured ferroelectricthin film materials sodium potassium niobate or Na0. LÄS MER
3. Towards Single-Ion Detection and Single-Photon Storage in Rare-Earth-Ion-Doped Crystals
Sammanfattning : Solid materials doped with rare-earth ions are considered an attractive platform for quantum information applications. One of the main reasons for this is the exceptionally long optical and hyperfine coherence times of the 4fn states, due to the shielding provided by the outer lying 5s and 5p electrons. LÄS MER
4. Electromechanical Interactions in Shuttle Systems and Carbon Nanotube Relays
Sammanfattning : In this thesis we theoretically investigate two kinds of nanoscale systems where there is a strong electromechanical coupling, i.e. an intricate relation between the Coulomb forces that can appear in these systems and the displacements of parts of the systems that they cause.
