 @inproceedings{chang_eskridge_2015, title={What Engineers Want: Lessons Learned from Five Years of Studying Engineering Library Users}, DOI={10.18260/p.25057}, abstractNote={Abstract It has long been recognized in the engineering library community that engineering faculty and students are a unique user group. Engineers don’t use libraries the way people in other disciplines do; the reason for this mainly lies in the engineering curriculum and the way engineering students are trained. Various studies over several decades have documented these differences and helped librarians to understand the engineering user and, ultimately, to design useful and responsive services to support this group effectively. It should then be of no surprise that, even as the broader user-experience movement has gained momentum in the library community and libraries have evolved their spaces and services for the 21st century, engineering librarians continue to seek opportunities to learn more about their users. Over the course of a five-year period from 2009-2014, engineering librarians at North Carolina State University conducted multiple studies of engineering faculty, graduate students and undergraduates to learn their preferences and use patterns with regard to library spaces, services and collections. These studies came about as a part of the planning and opening of a new library building, the James B. Hunt Jr. Library. Early studies were designed to contribute to the planning process for this building, while later ones supported decision-making in the implementation and post-occupancy phases. A variety of approaches were used including: in-depth interviews, focus groups, observational studies, and surveys. Particular emphasis was given to understanding faculty and graduate student needs to inform the design of dedicated spaces for these groups. The use of comparable methodologies before and after the opening of the library building allowed a comparison of these users’ predicted needs with their actual use and behavior. The resulting findings add to prior research on engineering library users and provide insights about this population in new library learning environments that can be applied beyond this institution. This paper will detail the studies conducted, the methodologies utilized in each case and discuss lessons learned about engineers as 21st century library users.}, booktitle={2015 ASEE Annual Conference and Exposition Proceedings}, publisher={American Society for Engineering Education}, author={Chang, Bertha and Eskridge, Honora}, year={2015} }

Films deposited under these conditions without IBAD exhibit fiber texture such that preferred (100) orientation exists perpendicular to the substrate. The orientation of the films has been studied as a function of ion bombardment angle, deposition rate, ion current density, and ion beam energy. Films deposited with IBAD at bombardment angles of less than 63° display strong (100) preferred orientation perpendicular to the substrate. Films having ion to atom ratios of 0.05 exhibit (220) biaxial alignment in the plane of the film. Best results were achieved for films with deposition rates of 2.4 Å/s, beam energies of 75 eV and ion fluences of 18 μA/cm2. Increasing the beam energy to 300 eV increases the concentration of wire texture in these films. Films deposited at higher ion/atom ratios (0.11 and 0.25) produce films with alignments highly dependent on the angle of ion bombardment. Processing conditions have been shown, therefore, to effect absolute orientation, and not just the quality of the pre-existing orientation. The microstructures of the biaxially aligned films have been studied and this has allowed for a clarification of the growth mechanism of these films. A growth instability of the differing orientations during ion bombardment is shown to cause in-plane alignment rather than preferential etching of misoriented nuclei.}, number={2}, journal={J. Appl.
