Nanoscale Depth-Resolved Point Defects at SrTiO3 Growth Surfaces

J. Zhang, D. Doutt, T. Merz, J. Chakhalian, M. Kareev, J. Liu, and L.J. Brillson
Chemically-etched SrTiO3 is widely used as a clean, atomically-smooth template for epitaxical growth of most complex oxides. Since native point defects in these materials are electrically-active and mobile, there is a need to lower their density. Download

Site-Specific Stamping of Graphene

D. Li, W. Windl, N.P. Padture
Graphene (2-D carbon) is being considered for spintronics due to its low spin-orbit coupling. While graphene-based devices are being made one-at-a-time successfully, there is a need for a high-throughput fabrication method.

X-ray Characterization of Self-Assembled Nanoscale Dielectrics

Jonathan D. Emery, Young-Geun Ha, Antonio Facchetti, Tobin J. Marks, Michael J. Bedzyk Northwestern University Materials Science and Engineering, NSF DMR-0520513; Dennis Keane, Qing Ma Argonne National Laboratory
Self-Assembled Nanoscale Dielectric (SAND) thin films are emerging as leading contenders in applications for organic and hybrid thin film transistors, allowing for low operating voltages and ideal device characteristics in next-generation flexible electronics.Â’  Dielectric properties are highly dependent on the behavior of the counter-anions within the film, specifically their position and motion under applied electric fields.Â’  Through utilization of advanced x-ray techniques, including long-period X-ray Standing Wave and X-ray Reflectivity, it is possible to locate and moni

Correlating the Structure, Optical Spectra, and Electrodynamics of Single Silver Nanocubes

Jeffrey M. McMahon, Yingmin Wang, Leif J. Sherry, Richard P. Van Duyne, Laurence D. Marks, Stephen K. Gray, and George C. Schatz Northwestern University Materials Research Science & Engineering Center, DMR-0520513
The plasmonic properties of noble metal nanoparticles have potential uses in a wide variety of technologies based on their optical response.Â’  Recent collaborative efforts of the NU-MRSEC demonstrate that correlated localized surface plasmon resonance (LSPR) spectroscopy and high-resolution transmission electron microscopy (HRTEM) measurements can be used to obtain the optical response and detailed structural information for a single nanoparticle.Â’  By carefully incorporating the HRTEM structural details into finite-difference time-domain (FDTD) electrodynamics calculations,

Chemical Doping of Organic Molecular Films for Photovoltaic Applications

Calvin Chan, Wei Zhao, and Antoine Kahn (Princeton) Stephen Barlow and Seth Marder (Georgia Tech)
To advance the application of organic molecular films in solar cells, PCCM researchers have improved their conductivity and carrier injection by n-doping the acceptor layer in a donor-acceptor cell. The acceptor was a fullerene layer, C60, while the dopant was the low-ionization-energy molecule decamethylcobaltocene (CoCp2*).
