(2012) IRG 2: Adding a Dimension to the Infrared Spectra of Interfaces using Heterodyne Detected 2D Sum-Frequency Generation (HD 2D SFG) Spectroscopy
By: IRG2: Wei Xiong, Jennifer E. Laaser, Randy D. Mehlenbacher , and Martin T. Zanni In the last ten years, two-dimensional infrared spectroscopy has become an important technique for studying molecular structures and dynamics. We report …
(2012) Education: Science Show from Puerto Rico Wows Madison Audiences
In July, 2012, the UW-MRSEC hosted graduate students from the University of Puerto Rico Mayaguez. While in Madison, Wisconsin the students performed their Science on Wheels (Ciencias en Ruedas) show at the Wisconsin Institutes for …
(2012) IRG 2: Controlling the Conductivity of ZnO Thin Films using Surface Chemistry
By: J. W. Spalenka, P. Gopalan, H. E. Katz, and P. G. Evans Solution deposited ZnO films have the opportunity for wide application in large-area electronics on flexible substrates, as transparent circuit elements, and as a …
(2011) UW MRSEC Hosts Two National Events for NISE Net Museum Educators
The University of Wisconsin – Madison (UW) Materials Research Science and Engineering Center (MRSEC) on Nanostructured Interfaces hosted two national events for museum educators at the Madison Children’s Museum and on the UW campus. The …
(2011) Transport in Ultra-Thin Silicon Membranes
Nanostructures are extremely sensitive to their surface properties. In the past year we have made extensive measurements of thin silicon films in ultra-high vacuum. We now have strong evidence that ultra-thin silicon with a 2×1 …
(2011) Semiconductor Nanomembrane Tubes: Three-Dimensional Confinement for Controlled Neurite Outgrowth
Semiconductor Nanomembrane Tubes: Three-Dimensional Confinement for Controlled Neurite Outgrowth (2011) In many neural culture studies, neurite migration on a flat, open surface does not reflect the three-dimensional (3D) microenvironment in vivo. With that in …
(2011) Phonon Scattering in Intrinsic Graphene using Tight-binding Bloch Waves
The overall interest in graphene as a material for devices has led to tremendous advances in the knowledge of transport in graphene. However, there are still questions about the intrinsic limit to electron mobility. Recent …
(2011) Mechanisms of Organic/Inorganic Interface Formation
Mechanisms of Organic/Inorganic Interface Formation (2011) Advanced organic/inorganic materials for applications including solar energy conversion and optoelectronics require the creation of interfaces with carefully controlled structural and electronic properties. Functional monolayers at these interfaces can …
(2011) Bridge-Dependent Interfacial Electron Transfer
Top: The kinetics of charge transfer from a rhenium-bypyridine complex to a TiO2 , measured for several molecular linkers (purple, black, red, and blue traces). Insets show the structure of the molecular systems, and infrared …
