In high speed devices, electrons are accelerated to high energy by a high electric field; to understand device performance, it is important to know how those “hot” electrons relax by scattering with each other and with the environment (the graphene lattice and the SiC substrate).
AlN, deposited by molecular beam epitaxy and patterned by electron beam lithography, forms an effective capping layer for epitaxial graphene growth on C-face SiC.
The list of potential curricular connections and activities that can be done with a wind tunnel in middle school is almost endless. This project incorporates simple geometry, weather, lab skills, metric measurement, as well as having the students work through the design process and actually construct and test their creations.
Sn whiskers are a serious reliability problem in Pb-free electronics manufacturing. Whiskers (as in fig. 1) grow out of pure Sn coatings and have been responsible for numerous system failures, such as the Galaxy IV satellite.
Graphene, an atomic layer of carbon atoms arranged in a honeycomb lattice, is actively being pursued as a material for next-generation electronics because of the high mobility of charge carriers and the potential to control their density by applying a gate voltage.
Dozens of excited middle and high school students from across Santa Barbara County spent a morning learning about alternative energy by building and racing their own solar cars. The workshop, presented as part of Science and Technology Day at UCSB, included a presentation on alternative energy, hands-on activities, and a corresponding video for teachers.
Initiative provides access to analytical instrumentation instruction to Minority Serving and Primarily Undergraduate Institutions through 4 types of virtual experiences: 1) User institution selects technique and class can access manuals, laboratories, and view training videos at http://www.mrfn.org 2) Live sessions through Skype fea
Mussel-inspired adhesion has much to teach about the chemistry and processing of polymers and provides a glimpse of some remarkable physical properties exhibited by this complex fluid. .
The Renewable Energy MRSEC at the Colorado School of Mines held a ten week Research Experiences for Undergraduates program on renewable energy in which over half of the 20 students were women.
