Nanofabrication using focused ion beam
Focused ion beam (FIB) technique uses a focused beam of ions to scan the surface of a specimen, analogous to the way scanning electron microscope (SEM) utilizes electrons. Recent developments in the FIB technology have led to beam spot size below 10 nm, which makes FIB suitable for nanofabrication. …

Focused Ion Beam Fabricated Non-equilibrium Superconducting Devices
The developments over the last decade in Focused Ion Beam (FIB) instrument technology have reached a point where there is sufficient control of an ion beam to make cuts, trenches, and other shapes in a sample on a scale of tens of nanometers. This work concentrates on the use of an FIB instrument …

Characterisation of focused ion beam nanostructures by transmission electron microscopy
Ion irradiation is an effective tool for the modifcation and control of the properties of magnetic thin films. Basic magnetic properties such as coercivity and local anisotropy direction can be altered in NiFe (Permalloy) films, whilst for Co/Pd multilayers, ion irradiation results in a transition …

Nanopore/Nanotube Pattern Formation through Focused Ion Beam Guided Anodization
Anodization is a kind of method that can produce oxide layer in a large area and on flexible shaped metals. In some specific conditions, anodic oxide layers exhibit interesting nanopore/nanotube structures. In this work, focused ion beam patterning method is introduced to general anodization, …

Characterization of ionic liquid ion sources for focused ion beam applications
In the Focused Ion Beam (FIB) technique, a beam of ions is reduced to nanometer dimensions using dedicated optics and directed to a substrate for patterning. This technique is widely used in micro- and nanofabrication for etching, material deposition, microscopy, and chemical surface analysis. …

Mechanisms of focused ion beam (FIB) material removal and rearrangement at high beam flux
Focused ion beam (FIB) is widely used as a material removal tool for applications ranging from electron microscope sample preparation to nanopore processing for DNA sequencing. Despite the wide spread use of FIB, the basic material removal mechanisms are not well understood and may depend upon FIB …

Increasing the bit density of a quantum confinement physically unclonable function
This dissertation presents work carried out in collaboration with the IMDEA nanoscience institute. We study the recently proposed quantum confinement physically unclonable function by Roberts, et al. that utilises resonant tunnelling diodes (physical representation of a quantum well) and atomic …

Unique Approaches to Interfacial Nanoscience
Other applications of the nanofabrication techniques are also explored. The nanopatterning of mica with a focused ion beam (FIB), shown for the first time here, has led to the formation of a wide variety of nanorod structures embedded in and supported by a number of different surfaces. The …
