The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...
Zinc tin oxide (ZTO) films deposited by pulsed laser deposition (PLD) are
investigated as a channel layers for transparent thin-film transistors (TTFTs).
Films are deposited on glass for characterization, and transistor channel layers are
deposited onto aluminum oxide-titanium oxide/tin doped indium oxide/glass
substrates (ATO/ITO/glass) to produce TTFTs.
UV-visible spectroscopy on...
A zeolite packed biofilter was retrofitted to a confined swine feeding operation in Eastern Washington, and evaluated for its ability to reduce the malodors from fan exhaust drawn from an internal under-slat manure storage pit. Ammonia (NH₃) was used as the representative constituent of swine waste malodor due to its...
You Stay Here is the beginning of a novel that centers on the notion of family, community, and the expectations that drive our interactions within these circles. The novel tells the story of brothers Mills and Nance O'Malley as they interact with their parents, Richard and Margaret. The brothers own...
The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...
Yeast mannoproteins released during the process of aging wine on the yeast lees have been reported to make important contributions to wine quality. However, few mannoproteins have been identified in wine and their lifespan during aging is unknown. As a first step towards better understanding the contributions of yeast mannoproteins...
We have performed fluorescence extended X-ray absorption fine structure (EXAFS) measurements on the Cd K-edge of partial electrolyte (PE) treated Cu(In[subscript 0.7]Ga[subscript 0.3])Se₂ (CIGS) thin film samples using synchrotron X-ray radiation. This data was compared to the EXAFS spectra of CdSe and CdO standards. Cd local structure models were constructed...
This collection of personal essays, inspired by Richard Rodriguez's Hunger of Memory, raises questions about the separation that becomes apparent through writing, education, and transitions between class. The author uses her personal experience of writing in, and attending a private university to explore the interactions of class, literacy, and education....
The purpose of this study was to explore wedding dress styles represented in United States high fashion magazines during the World War II period. The objectives of the study were to: discover what wedding dress styles were proposed by high fashion magazines during the period 1935-45, determine if wedding dress...
My thesis explains the several problems that arise when a person from a Western English speaking country goes to work as an English teacher at private institutes in South Korea. It is based on my own experiences when I worked as an English teacher at private institutes in South Korea...
With the arrival of European settlers to Western Oregon nearly 150 years ago came new methods of forest management. Early settlers' forest practices consisted of little more than harvesting what seemed an endless supply of timber. Forestry in the 20th century eventually incorporated such management concerns as re-forestation, biodiversity, wildlife...
Woody riparian vegetation is an essential component of riparian ecosystems, responsible in part for the maintenance of functional ecological processes. The plant community composition and distribution provide an indication of the underlying mosaic of environmental attributes and processes. Restoration and management of riparian communities have been hindered by the lack...
Light-frame construction practices and materials have changed greatly
over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...
In plantation forestry, rapid growth rate is favorable for wood production, but may decrease wood density, which is an important indicator of wood quality for both pulp and solid wood products. I looked for (1) differences in radial patterns of wood
density between planted and naturally grown Costa Rican tree...
The perception of the self as a sexual being is challenged by the
experience of pregnancy. Included in the experience of pregnancy are
issues with perceptions of the self, body image, transition into
motherhood, and reconciliation of the self as a sexual being during
pregnancy. Through a review of the...
This research is based on in-depth interviews with 20 women farmers and
ranchers from the state of Oregon. These women employ a variety of methods and
subscribe to a number of divergent philosophies regarding agricultural practices.
The intention of this study is to examine how women who are the primary...
Throughout society, many believe women are not succeeding professionally because of the institutional barriers created by men in the American workforce. However, women may be more competitive with other women than with men, especially when limited job positions are the goal. Competitiveness among women can be explained by a phenomenon...
Krascheninnikovia lanata (winterfat) is a valuable forage species with an
average of 10% crude protein during winter when there are few nutritious options for
livestock and wildlife. However, excessive grazing throughout the west has negatively
impacted survival of winterfat stands. We hypothesized that four years rest from
dormant season livestock...
The eight stories in Wild West Love Songs explore issues such as loss, suffering, and betrayal, but perhaps the most consistent theme is the examination of the ways we are haunted by our past. All the protagonists in these stories are haunted. Sometimes they are haunted literally, by a ghost...
This thesis examines the motivations of ecological restoration volunteers with the Oregon chapter of The Nature Conservancy. This study helps fill in voids left by a lack of research on the motivations of ecological restoration volunteers. Studies that have explored restoration volunteer motivation relied largely on surveys that revealed altruistic...
