Abstract:

This thesis describes the development of a rare gas metastable atomic beam apparatus, and its application to atom lithography. The principal component of the apparatus is the supersonic DC discharge source. The source parameters, such as operating pressure, skimmer distance, discharge current and nozzle shape were optimised to generate a bright beam of excited state metastable neon and argon, with typical flux of 5×10¹? atoms sr?¹ and 3×10¹? atoms sr?¹ respectively. This apparatus was used to investigate the pattern formation of self assembled monolayer (SAM) resists prepared on Au/Si samples

Abstract:

Using current technology, it is now possible to probe material at atomic length scales, increasing our fundamental understanding of material behavior and properties. Metastable β titanium alloys are a subset of titanium alloys with huge potential for the aerospace sector. However, they exhibit atomic transformations which, even after 60 years of research, are still disputed. For example, these alloys are strengthened using the ω phase, but the mechanism by which this phase forms and its stability are still in question. The aim of this PhD project was to investigate the strengthening of metasta

Abstract:

The low temperature form of the iron disilicide (P-FeSi2) phase has been widely shown to be a promising material for Si-based opto-electronics devices due to its direct band gap (0.87 eV). These materials can be easily produced using a wide range of techniques. This work focuses on two techniques that utilises an ion beam, ion beam assisted deposition (IBAD) and ion beam synthesis (IBS). IBAD has been identified as a suitable technique for producing low cost material over large areas, which is particularly important for applications as solar cells, McKinty et al (2002), This thesis reports in

The trap confines approximately 107 atoms, has a diameter of about 3 mm and with temperature approximately 1 mK. The trap is used for intra-trap and electron-atom scattering experiments. The results from these two experiments are reported. The electron scattering experiment is unique and employs a He* MOT for the first time, in c

Abstract:

Additive manufacturing processes of many alloys are known to develop texture during the deposition process due to the rapid reheating and the directionality of the dissipation of heat. Titanium alloys and with respect to this study beta titanium alloys are especially susceptible to these effects. This work examines Ti-20wt%V and Ti-12wt%Mo deposited under normal additive manufacturing process parameters to examine the texture of these beta-stabilized alloys. Both microstructures contained columnar prior beta grains 1-2 mm in length beginning at the substrate with no visible equiaxed grains.

Although more than 100 years have passed since its discovery, no cure for AD exists, despite enormous efforts in basic and clinical research over the past few decades, due to limited understanding of its underlying mechanisms.

A production of low velocity and monoenergetic atomic beams would increase the resolution in spectroscopic studies and many other experiments in atomic physics. Laser Cooling uses the radiation pressure to decelerate and cool atoms. The effusing from a glow discharge metastable argon atomic beam is affected by a counterpropagating laser light tuned to the cycling transition in argon. The Zeeman shift caused by a spatially varying magnetic field compensates for the changing Doppler shift that takes the atoms out of resonance as they decelerated.

The high temperature BCC phase (b) of titanium undergoes a martensitic transformation to HCP phase (a) upon cooling, but can be stabilized at room temperature by alloying with BCC transition metals such as Mo. There exists a metastable composition range within which the alloyed b phase separates into a + b upon equilibrium cooling but not when rapidly quenched. Compositional partitioning of the stabilizing element in as-quenched b microstructure creates nanoscale precipitates of a new simple hexagonal w phase, which considerably reduces ductility.

The high velocity of free atoms associated with the thermal motion, together with the velocity distribution of atoms has imposed the ultimate limitation on the precision of ultrahigh resolution spectroscopy. A sample consisting of low velocity atoms would provide a substantial improvement in spectroscopy resolution. To overcome the problem of thermal motion, atomic physicists have pursued two goals; first, the reduction of the thermal motion (cooling); and second, the confinement of the atoms by means of electromagnetic fields (trapping).

This thesis describes two separate investigations into the ionisation of the 3P2 metastable state of neon (Ne) by strong-eld light pulses. The first is an investigation into the ionisation yield of Ne and the second experiment examines the electron momentum distribution of the ionised electrons. Experimental ionisation results were compared to ionisation models via a scaling fit to ion yield and laser intensity. The best laser intensity fit was provided byTDSE based theory with n = 0:82. The effect of the spin state on ionisation yield was also examined, and it was determined that there is an

Abstract:

ScxAl1-xN and YxAl1-xN thin films were deposited in a ultra high vacuum system using reactive magnetron co-sputtering from elemental Al, Sc and Y targets in Ar/N2. Their mechanical, electrical, optical, and piezoelectrical properties were investigated with the help of transmission electron microscopy, xray diffraction, ellipsometry, I-V and C-V measurements, and two different techniques for piezoelectric characterization: piezoresponse force microscopy and double beam interferometry. Compared to AlN, improved electromechanical coupling and increase in piezoelectric response was found in ScxAl1
