Investigation of PAMBE grown InGaN/GaN double-heterojunction nanorods

Tu, Yen-Jie 26 July 2006 (has links)
The goal of this thesis is to grow InGaN at different temperatures in the form of GaN/InGaN double-heterojunction nanorods. XRD is used to analyze the In composition of film. PL, £g-PL, and CL are used to study the luminescence of InGaN and GaN, and calculation of In composition. For nanorods, the TEM and EDS are the tools to study the In composition and InGaN thickness. SEM is used to study the sample morphology. The work of EL has also been done in this thesis.

Seismic structure and earthquake focal mechanisms of the Hengill volcanic complex, SW Iceland

Miller, Angus D. January 1996 (has links)
Iceland provides a unique opportunity to study the processes that occur along mid- ocean ridges. In 1991, thirty temporary seismic stations were installed at the Hengill volcanic complex to record high-quality digital data from local earthquakes. From these data 449 earthquakes have been located, most of them beneath the geothermal area. A local earthquake tomographic inversion was carried out to determine the three- dimensional V(_p) and V(_p) /V(_s) structure to 6 km depth, using P-wave travel times and S-P times from local earthquakes recorded in 1981 and 1991. The resulting models are smoothly varying and give a low data variance. The V(_p) model is similar to that of a previous tomographic inversion in the area, although the models differ in detail. The main high-V(_p) features of these models are interpreted as solidified intrusions, and underlie extinct volcanic centres. A low V(_p) /V(_s) body (-4%) is detected from 0 to 3 km depth that correlates with the surface expression of the geothermal field and is probably due to a combination of effects that include a slightly lower pore fluid pressure (and thus a higher steam content), and rock matrix alteration. Well-constrained moment tensors were determined for 70 local earthquakes by inverting the polarities and amplitude ratios of P and S arrivals. This method works well and is relatively insensitive to wave-speed model and attenuation variations. Most of the earthquakes are non-double-couple with explosive volumetric components. Only 17 (28%) of the earthquakes are consistent with a double-couple model. The remaining earthquakes are modelled as a combination of an opening tensile crack and a shear fault. Two geometries are considered: (1) rupture on two separate fault planes aligned at 45º, and (2) opening-shear rupture on a single fault plane, which is equivalent to coplanar tensile and shear faults. Both models can give the same moment tensors, and the data cannot distinguish between them. They give a good fit to the data, with few polarity misfits for most of the earthquakes. Right-lateral opening-shear strike-slip faulting on near-vertical planes is consistent with the regional seismicity of the South Iceland Seismic Zone. The non-double-couple earthquakes may result from the regional stress regime interacting with the geothermal field.

The theoretical interaction between a fluid drop and a rigid solid /

Bachmann, Darren John. Unknown Date (has links)
The problem of determining the electrical double-layer interaction between a rigid planar surface and a deformable liquid droplet is formulated as a pair of coupled differential equations. The Young-Laplace equation, describing the shape of the droplet subject to a range of pressures, is solved numerically, while the linearized Poisson-Boltzmann equation, which describes the double-layer interaction is solved analytically. The van der Waals force is also considered. Results are provided over a wide range of boundary conditions, electrolyte concentrations and internal pressures. / Thesis (MSc(AppPhysics))--University of South Australia, 2001.
