6. A new synthetic strategy for low-dimensional compounds : Lone pair cations and alkaline earth spacers
Abstract : Complex transition metals oxyhalides containing a lone pair element, such as tellurium (IV), form an attractive research field because there is a high probability of finding new low-dimensionally arranged compounds and, particularly, a low-dimensionally arranged transition metals substructures, leading to interesting physical properties. Tellurium (IV) can drive the formation of many unusual structures because of its stereochemically active lone pair electrons, E. READ MORE

7. "Chemical scissors" - a shortcut to the low-dimensional world
Abstract : A number of oxo-halide compounds have been prepared and studied. The antimony Sb3+ cation shows great flexibility in adopting coordination numbers of three or four, and, since this ion carries a stereochemically active lone-pair of electrons (E), both coordinations are one-sided.

8. Feature Extraction for Low-Frequency Signal Classification
Abstract : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. READ MORE

9. Spin and charge in low-dimensional semiconductors
Abstract : In this thesis we investigate the trapping of spin-polarized electrons in edge states around a pair of antidots (Paper I). This study supports a proposal for using the trapped electrons to realize quantum gates - the building blocks of a quantum computer. READ MORE

10. Interactions, initial states, and low-dimensional semiconductors
Abstract : This thesis is concerned with different aspects of quantum mechanical interactions. The first part of the thesis focuses on their effects in low-dimensional semiconductors; the second part on one of their applications: quantum algorithms, which utilize superpositions created from quantum mechanical interactions.
