Abstract:

The study of photovoltaic materials is important so as to develop new solar energy technologies: in particular, quantum-confined semiconductors could offer increased quantum efficiencies at a much lower manufacture cost. This thesis contains results from a number of pump-probe experiments designed to probe the carrier dynamics in bulk and quantum-confined photovoltaics. A THz time-domain spectrometer was designed, built and commissioned. The THz refractive indices and absorption coefficients of toluene and hexane were determined, and the spectrometer was benchmarked using a photoexcited GaAs w

Abstract:

Identifying and treating infectious diseases remains a challenge for modern healthcare professionals. Proper identification of infectious diseases and understanding of the means of infection will allow for optimal use of antibiotics and the development of alternative therapies such as anti-adhesion therapy. It is therefore important to develop tools that can probe the processes involved in infection, or that can be used as point of care diagnostics. In vivo glycosylated surfaces are inherently heterogeneous, increasing the complexity of the interactions that take place, and with a correspondin

Abstract:

Atom probe tomography is a high resolution microscopy technique capable of determining the 3D location and chemical identification of individual atoms within a specimen. Though it is becoming ever more popular, a number of issues with the technique are known. First, the large amount of data created by atom probe tomography experiments requires new techniques to be developed so as to conduct effective analysis. Also, atom probe tomography is not traditionally considered a tool for crystallographic analysis even though crystallographic information is known to be present in reconstructed datasets

Abstract:

A combination of TEM and 3D atom probe has been used to study thin film magnetic materials for read head applications. Three different types of magnetic thin films have been investigated: (1) Co-based films for bias magnets, (2) magnetic tunnel junction (MTJ) with . AIOx barrier and (3) MTJ with MgO barrier. Unlike in longitudinal recording media, the Co-based films showed no Cr segregation to grain boundaries. This difference is likely to be due to the addition of Pt, which reduces the miscibility gap of the Co-Cr system, and film deposition at room temperature which reduces . the kinetics of

The morphology of cells changes consistently with the surface where they adhere.

Through the partial annealing method, SiOx substrates were fully covered with a mono-molecular

In this work we present electron beam techniques for probing the chiral structure of materials. The motivation for the work lies in two distinct aspects of chiral materials science. In the first case, chiral plasmonic excitations have recently been proposed for use in a variety of sensing technologies but require structural optimisation, in which modern electron microscopy techniques excel. In the second case, the recent development of intrinsically chiral electron ‘vortex beams’ suggests the prospect of being able to discriminate chiral crystal structures directly within the electron microsco

The term modification is used for manipulating the structures on a microscale by scraping them with a tiny tip.

Abstract:

The properties of quantum materials are determined by the delicate balance among many interacting degrees of freedom. The existence of several competing orders makes these systems highly susceptible to even small perturbations that can induce giant responses and eventually change the macroscopic state of the material. The microscopic understanding of the intricate interplay between electrons, ions and spins is thus the key to attain new material functionalities. Pump-probe optical experiments are a powerful tool to study the non-equilibrium states of quantum materials, offering unique insight

Hydrogen embrittlement (HE), which results in an unpredictable failure of metals, has been a major limitation in the design of critical components for a wide range of engineering applications, given the near-ubiquitous presence of hydrogen in their service environments. However, the exact mechanisms that underpin HE failure remain poorly understood. It is known that hydrogen, when free to diffuse in these materials, can tend to concentrate at a crack tip front. In turn, this facilitates crack propagation. Hence one of the proposed strategies for mitigating HE is to limit the content of freely

Abstract:

When azobenzene-modified photosensitive polymer films are irradiated with light interference patterns, topographic variations in the film develop that follow the electric field vector distribution resulting in the formation of surface relief grating (SRG). The exact correspondence of the electric field vector orientation in interference pattern in relation to the presence of local topographic minima or maxima of SRG is in general difficult to determine. In my thesis, we have established a systematic procedure to accomplish the correlation between different interference patterns and the topogra

Abstract:

Current magnetic data storage technology is encountering certain fundamental limitations that present roadblocks to its scalability to areal densities of 1 Tbit/in^2 and beyond. Next generation magnetic storage technology is expected to use optical near field techniques to heat the magnetic film locally to write data bits. This requires experimental measurement of thermal conductivity of materials with sub--100 nm resolution. This is essential for the tailoring of the thin film stack to optimize the heat transfer of the process. This can be accomplished with a simple modification to a traditio
