| The thesis is focused on the development of sensors based on advanced micro- and nano-structured carbon materials. In particular, we developed prototype diamond-based ultraviolet photodetectors and carbon nanotubes-based gas sensors. We describe the method of preparation and characterization of the active carbon-based materials and their structural and compositional characterizations. This is followed by the corresponding device fabrication and testing.;The thesis briefly gives an introduction to our current understanding about carbon materials, with emphasis on synthetic diamond and bamboo-like carbon nanotubes, and to the materials' properties that are useful for ultraviolet photodetectors and gas sensor applications. The thesis also give an overview of the experience gained through this research, and some suggestions for those who would like follow the research methods employ here. It provides experimental information learned through experience that may be helpful and avoid delays to the newer experimentalists. |
