Transport phenomena in thermoelectric and ferromagnetic nanostructures This thesis deals with transport phenomena in nanoscale systems: The Seebeck effect is explored in Bi2Te2 nanowires the anisotropic magnetothermal resistance effect in Ni nanowires and the giant magnetothermal resistance effect in Co Cu multilayers. Research on transport phenomena in a variety of materials has played a decisive role in the development of solid state physics and has led to important applications of functional materials e.g. for the conversion and storage of energy or in the field of storage and processing of data.
