Abstract:

As the limitations of current technology and the possibility of scaling down of technology becomes ever more apparent the drive for smaller, faster, cheaper and more sensitive devices gains momentum. Recent literature reports new and exciting possibilities with zinc oxide based one-dimensional nanomaterials rather than the popular carbon nanotubes. The attractiveness of these one-dimensional nanomaterials is the increased surface to volume ratios and the ability of this increased surface area to exhibit sensitivity to a range of gases by altering the conductivity upon absorption of molecules o

Abstract:

Fabrication and synthesis of nanostructured materials are essential aspects of nanoscience and nanotechnology. Although researchers are now able to create and tailor different nanostructured materials, the ability to precisely control the materials' sizes, shapes, and properties at the nanoscale level remains challenging. The aim of this dissertation was to develop new methods to aid researchers in overcoming these challenges. The study investigated two different methods used to create one-dimensional carbon nanostructures, i.e. carbon nanotubes and carbon nanopillars.In the first section, c

The ability to detect biomarkers at a molecular level is crucial to ensure high survival rates for patients with debilitating or life threatening diseases, for example cancer. The limitation associated with existing detection technologies call for more sensitive, selective, faster, cheaper and smaller biosensors for molecular analysis. Recent material advances made in One-dimensional (1-D) ZnO nanostructures hold great promise for fabricating the next generation of biosensors. Due to very high surface- to-volume ratios, they demonstrate high sensitivity to surface charge transfer and changes i

In this work, the optical properties of two kinds of one-dimensional (1D) nanomaterials, mesoporous silicon nanowires (mpSiNWs) and plasmonic nanospirals (NSs), were studied. These emerging nanomaterials are of great interest because of their fundamental structure-derived properties and potential practical applications. Four aspects of these materials were analyzed in this work. First, although the fabrication mechanism of mpSiNWs has been studied previously via metal-assisted chemical etching, the porosification-induced disturbance to the etching direction, which plays a vital role in control

In the past decades, the study of nanotechnology has brought in tremendous progress to the development of polymer electrolyte fuel cells (PEFC) and many advanced catalyst approaches have been developed. However, many of these still remain at ‘test-tube’ level and have not been implemented in practical fuel cells. The concerns about the gap between the pure material research and fuel cells are increasing, and a study focusing on the electrode structures is required to help address this issue.

Detection of explosive gas leaks such as hydrogen (H2) becomes key element in the wake of counter-terrorism threats, introduction of hydrogen powered vehicles and use of hydrogen as a fuel for space explorations.

Gas sensors properties such as sensitivity, selectivity and response time can be enhanced by tailoring the size, the shape, the structure and the surface of the nanostructures.

Abstract:

碩士<br>國立中山大學<br>電機工程學系研究所<br>96<br>In this study, we prepare the zinc oxide one-dimensional nanostructures with aqueous solution on GaN substrate. The morphologies of nanotip, nanorod and nanotube are formed with different modulation and chemical solutions. The thermal annealing with N2O ambiance at 300 °C for 1 hr increase the UV emission and decrease the defects. The limit of choosing the substrate to grow ZnO nanostructures is lattice mismatch between ZnO and substrate. The buffer layer is sputtered on substrate to remove the limit. The pattern of buffer layer also can be used for selective

Abstract:

博士<br>國立成功大學<br>微電子工程研究所碩博士班<br>94<br>In this study, both of the GaN nanocolumns (nanorods) and hollow nanocolumns (nanotubes) were formed successfully by inductively coupled plasma (ICP) etching without lithography technique. It was found that the tops of these nanostructures were hexagonal with the c-axis perpendicular to substrate surface confirmed by atomic force microscope (AFM) and scanning electron microscope (SEM). The density of the GaN nanocolumns depends strongly on etching parameters that suggests that the formation of these GaN nanostructures was not related to the dislocation den
