Surface Plasmons For Enhanced Metal-Semiconductor-Metal Photodetectors, Ayman A. Karar
Theses: Doctorates and Masters
Surface Plasmon Polaritons (SPPs) are quantized charge density oscillations that occur when a photon couples to the free electron gas of the metal at the interface between a metal and a dielectric. The extraordinary properties of SPP allow for sub-diffraction limit waveguiding and localized field enhancement. The emerging field of surface plasmonics has applied SPP coupling to a number of new and interesting applications, such as: Surface Enhanced Raman Spectroscopy (SERS), super lenses, nano-scale optical circuits, optical filters and SPP enhanced photodetectors. In the past decade, there have been several experimental and theoretical research and development activities which reported on …
Effect Of Thermal Annealing And Carbon Implantation On The Functional Properties Of Nanocomposite Tisin Coatings On Steel, Mohammad Shoeb Ahmed
Effect Of Thermal Annealing And Carbon Implantation On The Functional Properties Of Nanocomposite Tisin Coatings On Steel, Mohammad Shoeb Ahmed
Theses: Doctorates and Masters
This PhD research contributes to the part of advanced materials technology. The machining industry currently faces tremendous pressures with the need for durable cutting tools suitable for eco-friendly high speed machining operations becoming acute. In this thesis innovative design and synthesis strategies are explored to tailor the properties of nanocomposite coatings. Advanced characterisation techniques are applied to identify the mechanisms that control the mechanical, tribological, and corrosion behaviours of these coatings. Cutting tools protected by these coatings are anticipated to exhibit a unique combination of superior toughness and greater resistance to wear and corrosion, providing significant economic and environmental benefits. …
