Faculty Development and Campus Internationalization: A Case Study

148 leaves. Advisor: Thomas WestbrookFew studies have measured the impact of a short-term faculty overseas teaching experience on the internationalization of their home campus, through teaching, research, and service. This case study filled that gap and contributed to the understanding of the impact of bourgeoning educational exchanges between American and Chinese universities. The findings of this qualitative case study demonstrate a mixture of personal and professional motivations to participate in the Chinese Cultural Exchange Program between 2004 and 2008. Faculty who participated in CCEP contributed to campus internationalization in part by creating new courses, collecting data for research, adjusting teaching styles, working with international students and leading international programs and activities. In general, this study concluded that a short-term overseas teaching experience impacts on teaching, research, and service in the internationalizing a campus

A Case Study of a Successful Multicultural Project: CCEP and the Infusion of Internationalization across the University

Globalization has resulted in the call for greater diversity and multiculturalism in higher education. In order to achieve its stated goal of preparing students for “responsible global citizenship,” one master’s university1 has adopted an infusion model of internationalization. This study examines how the university’s Chinese Cultural Exchange Program (CCEP) contributed to those campus efforts to enhance multicultural or global awareness, specifically in regards to faculty and student exchanges

Direct Four-Probe Measurement of Grain-Boundary Resistivity and Mobility in Millimeter-Sized Graphene

Grain boundaries (GBs) in polycrystalline graphene scatter charge carriers, which reduces carrier mobility and limits graphene applications in high-speed electronics. Here we report the extraction of the resistivity of GBs and the effect of GBs on carrier mobility by direct four-probe measurements on millimeter-sized graphene bicrystals grown by chemical vapor deposition (CVD). To extract the GB resistivity and carrier mobility from direct four-probe intragrain and intergrain measurements, an electronically equivalent extended 2D GB region is defined based on Ohm’s law. Measurements on seven representative GBs find that the maximum resistivities are in the range of several kΩ·μm to more than 100 kΩ·μm. Furthermore, the mobility in these defective regions is reduced to 0.4–5.9‰ of the mobility of single-crystal, pristine graphene. Similarly, the effect of wrinkles on carrier transport can also be derived. The present approach provides a reliable way to directly probe charge-carrier scattering at GBs and can be further applied to evaluate the GB effect of other two-dimensional polycrystalline materials, such as transition-metal dichalcogenides (TMDCs)
