Contact-induced crystallinity for high-performance soluble acene-based transistors and circuits

March 8, 2008
Author(s)
David J. Gundlach, James E. Royer, SK Park, Sankar Subramanian, Oana Jurchescu, Behrang H. Hamadani, Andrew Moad, Regis J. Kline, LC Teague, Oleg A. Kirillov, Curt A. Richter, Lee J. Richter, Sean R. Parkin, Thomas Jackson, JE Anthony
The use of organic materials presents a tremendous opportunity to significantly impact the functionality and pervasiveness of large-area electronics. Commercialization of this technology requires reduction in manufacturing costs by exploiting inexpensive

Characterization of the Latent Image to Developed Image in Model EUV Photoresists

February 22, 2008
Author(s)
John T. Woodward IV, Kwang-Woo Choi, Vivek Prabhu, Shuhui Kang, Kristopher Lavery, Wen-Li Wu, Michael Leeson, Anuja De Silva, Nelson Felix, Christopher K. Ober
Current extreme ultraviolet (EUV) photoresist materials do not yet meet exposure-dose sensitivity, line-width roughness, and resolution requirements. In order to quantify how trade-offs are related to the materials properties of the resist and processing

Non-Brownian Microrheology of a Fluid Gel Interface

February 20, 2008
Author(s)
Erik K. Hobbie, Sheng Lin-Gibson, S K. Kumar
We use stroboscopic video microscopy to study the motion of a sheared fluid-gel interface. External mechanical noise plays a role analogous to temperature, but with a low-frequency breakdown of linear response consistent with an underlying instability. We

High throughput adhesion testing using a modified edge lift-off test

February 17, 2008
Author(s)
Jiong Liu, Martin Chiang, Michael J. Fasolka, Christopher Stafford
The strength of an adhesively bonded joint depends on a host of factors such as surface treatment, roughness, materials properties, cure conditions and environmental variables. Therefore testing of adhesion within this large parameter space can be very

JKR Adhesion Testing Between Biologically Relevant Surfaces

February 17, 2008
Author(s)
Adam J. Nolte, Heqing Huang, Christopher Stafford
In this work we report recent observations obtained using an adhesion testing device that utilizes the contact mechanics theory of Johnson, Kendall, and Roberts (JKR). Our goal is to develop a system capable of measuring adhesive forces between

Single cantilever peel test for analysis of adhesion strength in nanotransfer printing

February 17, 2008
Author(s)
Deuk Y. Lee, Gottlieb Oehrlein, Daniel R. Hines, Jiong Liu, Jun Y. Chung, Christopher Stafford, Christopher Soles, Eric K. Lin
Nanotransfer printing (NTP) has attracted much attention as a method for fabricating nanoscale structures using materials that are not generally compatible with conventional lithographic techniques. For NTP of a polymer film to a polymer substrate, thermal

Combinatorial Methodology for the Exploration of Metal Gate Electrodes on HfO 2 for the Advanced Gate Stack

January 23, 2008
Author(s)
Kao-Shuo Chang, Martin L. Green, John S. Suehle, Jason Hattrick-Simpers, Ichiro Takeuchi, K Ohmori, T Chikyow, S De Gendt, Prashant Majhi
Combinatorial methodology offers an efficient platform to accelerate the exploration of new materials. We demonstrate the effectiveness of this technique on the study of new metal gates for the advanced gate stack. We report two examples, Ni-Ti-Pt ternary

The Modified-Single Fiber Test: A Methodology for Monitoring Ballistic Performance

January 18, 2008
Author(s)
Jae Hyun Kim, Walter G. McDonough, William R. Blair, Gale A. Holmes
In an effort to develop a minimally invasive testing methodology for monitoring the in-service performance of soft body armor, the ASTM D3379-75 standard was modified by measuring the fiber diameter at 5 equally spaced locations along a 6 cm gauge length

On the nature of asymetry of nucleation centers activity in ultrathin Co films and Co/Pt multilayers

January 14, 2008
Author(s)
Yu L. Iunin, Yury P. Kabanov, Valerian I. Nikitenko, X M. Cheng, Alexander J. Shapiro, C L. Chien, Robert D. Shull
Magnetization reversal in ultrathin Pt(10 nm)/Co(0.6 nm)/Pt(3 nm) magnetic films and Pt(10 nm)/[Co(d)/Pt(1 nm)]_n}/ Pt(2 nm) (d = 0.4, 0.6, 0.8 nm, n = 2, 4) multilayers with perpendicular anisotropy has been studied using Kerr microscopy. These materials

Model for Reversible Nanoparticle Assembly in a Polymer Matrix

January 8, 2008
Author(s)
Andrew Rahedi, Jack F. Douglas, Francis W. Starr
The clustering of nanoparticles (NP) within solutions and polymer melts depends sensitively on the strength and directionality of the NP interactions involved, as well as the molecular geometry and interactions of the dispersing fluids. Since clustering

A Device for Mechanically Folding Yarns and Woven Fabrics of Ballistic Fibers

January 7, 2008
Author(s)
Walter G. McDonough, Jae Hyun Kim, Nolan J. Brandenburg, William R. Blair, Gale A. Holmes
Abstract (2000 characters maximum - spell out acronyms the first time)An apparatus was designed and built that attaches to servo-hydraulic machines that typically perform material fatigue testing. The device was designed to systematically fold woven fabric

Multiscale modeling of point defects in strained silicon

December 31, 2007
Author(s)
Vinod Tewary, B. Yang
A multiscale Green's function method is described for modeling substitutional point defects and vacancies in strained silicon. The model seamlessly links the length scales from atomistic to macro. The model accounts for the discrete lattice effects
