Highly-ordered graphene for two dimensional electronics

With expanding interest in graphene-based electronics, it is crucial that high quality graphene films be grown. Sublimation of Si from the 4H-SiC(0001) Si-terminated) surface in ultrahigh vacuum is a demonstrated method to produce epitaxial graphene sheets on a semiconductor. In this paper we show that graphene grown from the SiC$(000\bar{1})$ (C-terminated) surface are of higher quality than those previously grown on SiC(0001). Graphene grown on the C-face can have structural domain sizes more than three times larger than those grown on the Si-face while at the same time reducing SiC substrate disorder from sublimation by an order of magnitude.Comment: Submitted to Appl. Phys. Let

Issues of Racial, Ethnic, and Gender Diversity in Preparing School Administrators

The four authors teach in the Department of Educational Leadership at the University of Dayton. Each taught a new course that addressed issues of diversity in schools, focusing on race, ethnicity, and gender. Each developed the course in a unique way and in distinct settings, though each involved: 1. Reflecting holistically on the experience of teaching the course in order to generate common themes explaining what the experience meant to the faculty as individuals and as women (Blackmore & Kenway, 1993). 2. Examining students\u27 work, behaviors, communication, and attitudes in order to infer level of, as well as changes in, racial, gender, and cultural maturity. 3. Drawing implications for programs in educational leadership from the course experiences and developing a model of sharing scholarship. The purpose of this chapter is to bring together each educator\u27s story to draw conclusions about how students in educational administration might most effectively learn to understand the perspectives of those unlike themselves and might most effectively lead in the diverse communities where they will most likely serve

Adding Soft-Skills to the Hard Target of Adequacy: The Case for Rearticulation Based on a Multifocal Analysis

The purpose of this study is to expand the definition of adequacy by adding soft skills as a measure of school productivity. The singular focus on academic standards inherent in education policy has prevented scholars from seeing the concept of adequacy through myriad perspectives and has contributed to a resegregation of schools. Education policy includes legal, historical, and political perspectives; research inquiries must accommodate these multiple foci. This study made use of multifocal analysis to investigate the development of the concept of adequacy in South Carolina. Conclusions suggest an expanded definition of adequacy has potential for addressing school financing policy, but also for making historical, political and legal contributions to educational and economic policies aimed at repurposing schools

Early childhood adversity and adolescent depression: the mediating role of continued stress

Background. While various conceptualizations of the link between childhood adversity and later depression have been offered, most have not accounted for the possibility that early adversity predicts continuing stress proximal to depression onset. Thus, the present study tested the possible mediating role of recent stress in the association between early adversity and depression in late adolescence
