Mansour, Ahmad Ibrahim

This thesis studies the intrinsic disorder effects and the transport and magnetic properties of ring-shaped epitaxial thin films and superconducting tunnel junctions (STJs) of the high temperature superconductor YBa$2$Cu$3$O${7-\delta}$. We used an unconventional contactless technique that allows...

Tucker, Ryan T.

Nanoscale materials offer opportunities to employ unique physical phenomena and performance enhancement in many applications, including energy conversion. The coupling of functional materials properties and nanoscale morphologies is paramount for the successful implementation of nanostructured...

Lalany, Abeed

The use of organic, semiconducting polymers provides an attractive option to advance commercial solar photovoltaic technologies. These devices have the potential to be spray-coated on flexible, light-weight substrates and produced cheaply in high volumes; however, performance remains limited in...

Hu, Huan

Metamaterials are artificially engineered materials with tailored properties for applications in imaging, sensing, waveguiding and quantum optics. Even though they hold the potential for transformative impact, industrial applications have been impeded by large absorption losses in material...

Zhang, Yun

Nanofabricated optically anisotropic uniaxial thin films with deep submicron feature sizes are emerging as potential platforms for low-loss all-dielectric meta-materials and for Dyakonov surface wave-based sub-wavelength optical confinement and guiding at interfaces with isotropic media. In this...

Kohandehghan, Alireza

This thesis is focused on the silicon-based anode materials for lithium-ion batteries (LIBs) as well as germanium-based electrode materials for sodium-ion batteries (NIBs). In our first attempt we studied electrochemical cycling stability and degradation mechanisms of silicon nanowires (SiNWs)...

Mohammadpour, Arash

The n-type semiconducting, vertically oriented TiO2 nanotube and nanowire arrays constitute a mechanically robust, high surface area, easily functionalized architecture with vectorial electron percolation pathways and have been the focus of interest for variety of applications including but not...
