Manipulating Anisotropic Transport and Superconductivity by Focused Ion Beam Microstructuring by Maja D. Bachmann Pdf

This thesis presents pioneering work in the relatively new field of focused ion beam (FIB) sculpting of single crystals to produce bespoke devices and enable the investigation of physics that cannot be studied in bulk samples. It begins with a comprehensive and didactic account of how to achieve this sculpting, revealing the ‘tricks of the trade’ of state-of-the-art FIB microstructuring. In subsequent chapters, the author presents ground-breaking results obtained from microstructures of the delafossite oxide metal PdCoO2 and the heavy fermion superconductor CeIrIn5. In these elegant, forefront experiments, a new form of directional ballistic transport in the ultra-pure delafossites is described and explained. Furthermore, a new way to spatially modulate superconductivity induced by strain is demonstrated with electrical transport measurements that agree well with predictions based on thermoelastic finite element simulations.

Probing Unconventional Transport Regimes in Delafossite Metals by Philippa H. McGuinness Pdf

This thesis describes in-depth studies of the remarkable electronic transport within the ultrahigh conductivity delafossite metals PtCoO_2 and PdCoO_2 using the tool of focused ion beam (FIB) microstucturing. Despite being first synthesised over 50 years ago, important questions remain regarding both the origin of the unusually high conductivity of these compounds and the consequences of their unique properties for unconventional electronic transport, such as that within the ballistic regime. The thesis explores both these areas. High-energy electron irradiation is used to examine the effects of deliberately introducing point defects into PdCoO_2 and PtCoO_2, demonstrating that the extremely low resistivity of these materials stems from an extreme purity as high as 1 defect in 120,000 atoms, rather than a novel scattering suppression mechanism. In addition, studies of the electronic transport in micron-scale squares of these metals show that their broadly hexagonal Fermi surfaces lead not only to long range ballistic behaviour but novel ballistic regime phenomena which cannot be observed in materials with a higher-symmetry Fermi surface.

Functional Nanostructures Fabricated by Focused Electron/Ion Beam Induced Deposition by Rosa Córdoba Castillo Pdf

This thesis constitutes a detailed study of functional nanostructures (ferromagnetic, superconducting, metallic and semiconducting) fabricated by focused electron/ion beam induced deposition techniques. The nanostructures were grown using different precursor materials such as Co2(CO)8, Fe2(CO)9, W(CO)6, (CH3)3Pt(CpCH3) and were characterized by a wide range of techniques. This work reports results obtained for the morphology, the microstructure, the composition, the electrical transport mechanism, magnetic and superconducting properties of nanostructures. The results offers exciting prospects in a wide range of applications in nanotechnology and condensed matter physics.
