Conduction and Dielectric Relaxation Mechanisms in Oil Sands Influencing Electrical Heating
DownloadFall 2016
Electrical heating has been proposed in the past as an alternative to conventional water based thermal methods for reducing viscosity of bitumen in oil sands reservoirs. This could reduce or even eliminate water use and associated problems like inefficient heat transfer in the reservoir, poor...

In this thesis, we propose the use of the polarization camera for high-dynamic-range (HDR) imaging. Specifically, observing that natural light can be attenuated differently by varying the orientation of the polarization filter, we treat the multiple images captured by the polarization camera as a...

Deposition and Characterization of AlN and GaN Thin Films by Plasma-Enhanced Atomic Layer Deposition
DownloadSpring 2015
III-nitride semiconductors have a combination of structural characteristics and engineering properties that give them a unique place among semiconductors. The fact that they have the same crystal structure makes it possible to deposit alloys with fine-tuned band gaps from infrared to ultraviolet...

Engineering Considerations for the Design of High Performance Zinc Oxide Thin Film Transistors
DownloadSpring 2018
Zinc oxide (ZnO) thin film transistors (TFTs) are garnering significant interest recently due to their unique combination of high optical transparency, moderately high electron mobility, good stability, and compatibility with low temperature processing. If a low temperature processed, high...
