Characterization of carbon nanotubes grown by chemical vapour deposition
Ahmed, Muhammad Shafiq (2009-08-01)Carbon nanotubes (CNTs), discovered by Ijima in 1991, are one of the allotropes of carbon, and can be described as cylinders of graphene sheet capped by hemifullerenes. CNTs have excellent electrical, mechanical, thermal ... -
Empirically detecting colour: can we use solar cells as colour sensors?
Majluf Suárez, Sergio (2021-08-01)The purpose of this thesis was to explore the possibility of using solar cells as a colour sensor. Colour sensors already exist, yet they are either costly or fail at correctly sensing monochromatic light. Our experiment ... -
Graphene and graphane functionalization using hydrogen and nitrogen electronic optical and vibrational signatures
McNelles, Phillip (2011-04-01)Hydrogen is added to Graphene in various compositions and configurations to modify the band structure to produce a suitable band gap for microelectronic applications. Optical and vibrational spectra are calculated as a ... -
Investigation of dye-sensitized solar cell performance with single chirality semiconducting carbon nanotubes
Davis, Victoria (2015-03-01)In this work, the performance, electrical transport, and optical properties of dye-sensitized solar cells (DSSCs) assembled with single-walled carbon nanotubes (SWNTs) of a single chirality in the photoanode were ... -
Nanostructured materials for photovoltaics and microwave electronics: methods and applications
Quaranta, Simone (2017-04-01)Nanoscale particles and thin layers are today used for a variety of applications to make industrial products lighter, stronger or more conductive. This study investigates synthesis, characterization and application of ... -
Radiation response and optical characterization of carbon based thin-films prepared by saddle field plasma enhanced chemical vapor deposition
Hegazy, Sameh (2020-09-01)Carbon based thin-film materials have been attracting a lot of attention in many research fields due to their unique material properties. Detection of ionizing radiation is an important application that carbon and diamond ... -
Synthesis and characterization of nanostructured catalysts for photovoltaic applications
McGillivray, Donald (2013-07-01)The objective of this project was to investigate the effect of the morphology of titanium dioxide (TiO2) nanoparticles on the electron transport properties and light harvesting potential in a dye sensitized solar cell ...
