Graphene as Transparent Electrode for Direct Observation of Hole Photoemission from Silicon to Oxide

March 27, 2013
Author(s)
Rusen Yan, Qin Zhang, Oleg A. Kirillov, Wei Li, James I. Basham, Alexander G. Boosalis, Xuelei X. Liang, Debdeep Jena, Curt A. Richter, Alan C. Seabaugh, David J. Gundlach, Huili G. Xing, Nhan V. Nguyen
The outstanding electrical and optical properties of graphene make it an excellent alternative as a transparent electrode. Here we demonstrate the application of graphene as collector material in internal photoemission (IPE) spectroscopy; enabling the

Towards the Integration of Carbon Nanotubes as Vias in Monolithic 3D Integrated Circuits

Carbon nanotubes (CNT) can be an attractive candidate for vertical interconnects (vias) in 3D integrated circuits due to their excellent thermal and electrical properties. To investigate CNT electrical resistivity, test vias were fabricated using both a

Polymer chain dynamics in weakly intercalated polymer/nanoplatelet mixtures

March 15, 2013

Kevin A. Masser, Hongyi Yuan, Chad R. Snyder, Alamgir Karim
The dynamics of two chemically similar type-A polymers, poly(epsilon-caprolactone) (PCL) and poly(lactic acid) (PLA) with small amounts of Cloisite 30B nanoplatelets were investigated via broadband dielectric relaxation spectroscopy. The terminal

Adhesion Society Meeting Proceedings

Rebecca Ploeger, Aaron Forster, Donald Hunston, Etienne de la Rie, Christopher McGlinchey
Consolidating adhesives have been used throughout the centuries for the conservation of painted cultural objects- such as paintings and polychrome sculpture- and if it were not for these adhesives, many objects may not have survived to the present day

Gradient Nanofiber Scaffold Libraries for Screening Cell Response to Poly(e-caprolactone)-Calcium Phosphate Composites

March 1, 2013

Carl G. Simon Jr., Limin Sun, Laurence C. Chow, William Miles, Christopher K. Tison, Kaushik Chatterjee, Marian F. Young, Vinoy Thomas, Murugan Ramalingam
A 2-spinnerette approach has been developed for fabricating nanofiber scaffold gradients for use as 1) scaffold libraries for screening the effect of nanofiber properties on cell response and 2) templates for generating graded tissue interfaces. Although

Organosilicate Polymer E-Beam Resists with High Resolution, Sensitivity and Stability

Christopher Soles, Richard Kasica, Hae-Jeong Lee, Jae H. Sim, Sung-Il Lee, Ki-Bum Kim, Hyun-Mi Kim, Do Y. Yoon
Hydrogen silsesquioxane (HSQ) is an attractive electron-beam (e-beam) resist for sub-20 nm lithography due to its high resolution, excellent line-edge-roughness (LER), and good plasma etch resistance. However, the sensitivity and long-term stability of HSQ

Markup Instructions for Extended Friction Ridge Features

February 5, 2013

Melissa Taylor, Will Chapman, Austin Hicklin, George Kiebuzinski, Peter Komarinski, John Mayer-Splain, Rachel Wallner
This document provides instructions for latent print examiners in marking friction ridge features to maximize consistency among examiners. This document builds upon the Extended Feature Set (EFS) defined in American National Standards Institute/National

Spontaneous wrinkling in azlactone-based functional polymer thin films in 2d and 3d geometries for guided nanopatterning

February 4, 2013

Muruganathan Ramanathan, Bradley S. Lokitz, Jamie M. Messman, Christopher Stafford, S. M. Kilbey
We report a simple, one step process for developing wrinkling patterns in azlactone-based polymer thin films and brushes in 2D and 3D surfaces. The polymer used in this work wrinkles spontaneously upon deposition and solidification on a substrate without

Stratified Graphene-Noble Metal Systems for Low-Loss Plasmonics Applications

January 30, 2013
Author(s)
Anna L. Rast, Timothy Sullivan, Vinod K. Tewary
We demonstrate numerically that bulk plasmon losses in noble metal films can be significantly reduced through the addition of a graphene coating and hexagonal boron nitride substrate. Silver films with a trilayer graphene coating and hBN substrate

Submicrometer-Resolution Polychromatic 3D X-Ray Microscopy

January 15, 2013
Author(s)
B C. Larson, Lyle E. Levine
The ability to study the structure, microstructure, and evolution of materials with increasing spatial resolution is fundamental to achieving a full understanding of the underlying science of materials. Polychromatic 3D x-ray microscopy (3DXM) is a

Extended Feature Set Profile Specification

January 14, 2013
Author(s)
Melissa Taylor, Will Chapman, Austin Hicklin, George Kiebuzinski, John Mayer-Splain, Rachel Wallner, Peter Komarinski
This specification defines Extended Feature Set (EFS) Profiles - sets of features to be used in latent friction ridge (fingerprint, palmprint or plantar) searches of automated friction ridge identification systems (AFIS). The EFS Profiles are designed to
