Layered multiconductor coupled slot and strip-slot structures are characterized by introducing the full-wave modal analysis as well as the quasi-TEM spectral domain technique. In the modal analysis, the electric and ma ...

A complete Gallium Arsenide Metal Semiconconductor Field Effect Transistor (GaAs MESFET) model including deep-level trap effects has been developed, which is far more accurate than previous equivalent circuit models, ...

Fiber-optic-coupled dosimeters (FOCDs) are a relatively new method in which to obtain in-vivo dose concomitant with radiation treatment. Accurate live dosing can be achieved virtually anywhere due to their small dimensio ...

This thesis focuses on two aspects of oxide-based thin-film transistors (TFTs), contact resistance and instability assessment. First, determination of the contact resistance of indium tin oxide (ITO) on two wide-band ga ...

In this dissertation, a new Δ∑ A/D converter is presented that is ideally suited for communication applications. It is based on a single-loop single-stage structure, which can realize a high maximum out-of-band quantiz ...

Polymer electrolyte membrane (PEM) fuel cells are being studied for use as high efficiency power plants in alternative fuel vehicles. To maintain high efficiency the operating temperatures of the membranes in these fuel ...

ZnO nanowires (NWs) are good candidates for chemical sensing because of their high surface-to-volume ratio. In this work, ZnO nanobridge sensors were fabricated utilizing a novel method which uses carbonized photoresist ...

Two methods of electro-optically characterizing alternating-current thin-film electroluminescent (ACTFEL) devices are investigated: photo-induced transferred charge (PIQ) and luminescence (PIL), and subthreshold voltag ...

The focus of this thesis involves developing general fabrication processes relevant to the manufacture of two new devices for the Microscale technology Energy and Chemical Systems (MECS) program at Oregon State Univers ...
