2. Atom-Probe Field-Ion Microscopy of Electronic Materials
Abstract : This thesis presents work in which atom-probe field-ion microscopy (APFIM) has been applied to two types of electronic materials. In the case of metal/GaAs contacts, the purpose was to characterise the microstructure of the contact interface, particularly the chemical composition variation across the interface. READ MORE

3. Atom Probe Field Ion Microscopy of Surface Zones, Coatings and Interfaces
Abstract : This thesis is focused on developingmethods for high resolution microanalysis of coatings on a substrate, andsurface zones of a bulk sample using atom probe field ion microscopy,APFIM. The APFIM technique is described and some examples of its applications to semiconductors,cemented carbides and intermetallic compounds are given. READ MORE

5. Fabrication of Low-Dimensional Structures in III-V Semiconductors
Abstract : The thesis presents studies on the processing technology and the characterization of nanometer-sized and low-dimensional structures in III-V semiconductors. Two major approaches are described: 1) the combination of aerosol technology and plasma etching for the fabrication of quantum dots (QDs) in InP-based materials and 2) the use of high-resolution electron beam lithography and plasma or wet chemical etching to make quantum well wires (QWWs) in both GaAs and InP-based structures.
