Local Events Spotlight REU Researchers Jun Jiao (Portland State University), DMR 0649280

1. Local Events Spotlight REU ResearchersJun Jiao (Portland State University),DMR 0649280 • REU students presented at the Fourth Annual Student Research Symposium hosted by the Columbia-Willamette Chapter of Sigma Xi: • Rebecca Schaller, REU, worked with graduate student Devon McClain in collaboration with Intel on the Impact of Oxygen Absorption on a Large Population of Carbon Nanutube Field Effect Transistors (CNFET). • Their poster won 2nd Place Research Award and a manuscript based on this work was submitted to Nano Letter. • They concluded that the presence of or absence of gas molecules effect the CNFET and recognized the importance of looking at a large population of devices to gauge how CNFET behave. • Molly Juhlin, REU, presented her finding on the Biological Electron Microscopy of Archaea and their viruses and outlined ways to use SEM and TEM technology to characterize viruses in the domain Achaea. • 2008 OHSU Northwest Undergraduate Conference allows participants a chance to give oral presentations of original research: • Rebecca Schaller, REU, talked about Fabrication and Testing of Carbon Nanotube Field Effect Transistors which is important to further the study of nano-devices and learn more about the behavior of CNT-FETs. • Participating in events such as these provide practice for presentations at regional and national meetings and highlight important research being conducted.

2. REU Field Trip to Area High-Tech CompanyJun Jiao (Portland State University),DMR 0649280 One of the broader impacts of the REU program at Portland State University (PSU) is the field trip to FEI, the award leader in making electron microscopes, focus ion beam systems, and ion/electron emitters. Since the REU participants use microscopes made by FEI, it is important to understand where this technology is created.Students are given an opportunity to interact with professionals in their field, gain a better understanding of how the industry works, and observe various demonstrations on a variety of instruments. Students are trained on a Scanning Electron Microscope (SEM), a Transmission Electron Microscope (TEM), and a Focused Ion Beam Microscope (FIB) at the Center for Electron Microscopy and Nanofabrication (CEMN) at PSU during the REU training week. Participants will continue to work with these microscopes while conducting research with their faculty adviser in the lab on a variety of subjects including Chemistry, Physics, Biology, Environmental Science, and Geology. FEI is a strong supporter of the REU program and graciously hosts the REU participants every year, leading an in-depth tour of their facilities, providing lunch, and sending each participant home with a gift bag. FEI continues to partner with the REU program and will be hosting participants of the 2008 REU program this July.
