As advances in silicone CMOS technology steadily plateau, new avenues of electronics design must be explored. Graphene Nanoribbons (GNRs) are a potential solution. Current GNR designs require wasteful exhaustive searches for the required device topologies, limiting the size of the solution space that can be searched. This is fine for simple...

Electronic interfaces, particularly microelectrode arrays (MEAs), are crucial for studying electrophysiological processes in the body, with applications ranging from implants to deep brain simulators. In neuroscience, they play a vital role in exploring neuronal cell distribution and behaviour, as well as disorders like epilepsy and Alzheimer’s...

As silicon carbide(SiC) gets more and more attention from the semiconductor industry due to its robust mechanical and chemical properties, reliable and standardized processing technologies such as reactive ion etching(RIE) for SiC are in great demand. This is because of the difficulty and challenge of fabricating micro devices on the SiC...

Numerous advancements have been made in transparent electrode technologies that can complement optogenetics and imaging modalities. However, several obstacles restrict the design and material of electrode devices, including the required flexibility, transparency, low impedance, high charge storage<br/>capacity (CSC), and high charge injection...

Metal oxide nanoparticle gas sensors showpromise due to their high sensitivity towards a wide range of gases, low costs, and low complexity. Particle sizes at nanometers offer a high surface-to-volume ratio which provides more areas on the surface where reactions can occur. This work presents the application of spark ablated nanoparticles on...

To extend Moore’s law, silicon carbide devices attend the researcher’s attention due to their irreplaceable advantages such as high critical breakdown electrical field, wide bandgap and excellent thermal conductivity without sacrificing too much charge carrier mobility. However, the defects on the SiC-oxide interface degrades the performance of...

Graphene as an allotrope of carbon is promising for the detection of gaseous molecules due to its extremely high surface-to-volume ratio. However, its low selectivity poses a major problem for practical applications. The work presented in this thesis addresses the selectivity problem by depositing metal/metal oxide nanoparticles (NPs) on the...

The evolution of microphone technology can be linked to the growing multimedia and communication market. The first is linked to the music and audiovisual industry, while the latter is linked to smartphones, smart mobility, and home automation. In all of these audio applications, the common trend is toward downsizing and performance improvement....

Localization of a light source in the space requires capturing its light intensity and angle information. However, conventional CMOS image sensors can only capture light intensity and wavelength. These sensors need to be augmented with an optical extension such as an aperture or a lens in order to capture the angle information. The use of...

Silicon-based MEMS technology has been the standard for developing 2D and 3D<br/>micro-structures for many years. There are 2 main classifications of MEMS manufacturing technologies, viz. bulk micro-machining, and surface micro-machining.<br/>These techniques have its own set of drawbacks. Bulk micro-machining affects the structural integrity of...

Neuroscientists use neural electrodes to explore the working mechanisms of the nervous system. Therefore, ideal electrodes should have a small size and the ability to record and stimulate at a single cell resolution with low noise. Materials used for fabrication should be flexible and stable for a long period in the biological media. However,...

Superconducting resonators used in mm/sub-mm (MMW) astronomy would greatly benefit from deposited dielectrics with low dielectric loss. The excess loss in deposited dielectrics is mainly due to two-level systems (TLS), and there is no consensus on their microscopic origin. To study the relation between hydrogenated amorphous silicon’s (a-Si:H)...

Graphene is an attractive material to be used for pressure sensors due to its thinness, electrical conductivity, and potential high gauge factor. One of the issues with processing graphene is the scalability, which is largely limited by the transfer process that is required for graphene deposited by chemical vapour deposition (CVD). In this work...

This thesis has explored the possibility of using carbon nanotubes (CNT) as a novel material for through-silicon vias (TSV) in 3D-integrated circuits. With the steady downscaling trend of the semiconductor industry, a major limiting factor to the overall performance of the device is the delay from interconnects; a trend that is worsening over...
