   Nyckelord :Inorganic chemistry; Atomic layer deposition; Metal oxide; Nanostructures; Template deposition; Thin films; Oorganisk kemi;

   Sammanfattning : Thin films of cobalt oxide, iron oxide and niobium oxide, and nanostructured thin films of iron oxide, titanium oxide and multilayered iron oxide/titanium oxide have been deposited by Atomic Layer Deposition (ALD). The metal oxides were grown using the precursor combinations CoI2/O2, Fe(Cp)2/O2, NbI5/O2 and TiI4/H2O. LÄS MER

5. 9. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films
