Characterizing the Mechanical Properties and Degradation of Thin Polymer Membranes

August 28, 2011
Author(s)
Christopher M. Stafford, Jun Y. Chung, Junghyun Lee
The elasticity, strength, and toughness of thin polymer membranes are of considerable interest since direct knowledge of these key mechanical properties can provide insight into performance, durability, and underlying degradation mechanisms that occur over

Effect of Regioregularity on the Semicrystalline Structure of Poly(3-hexylthiophene

August 25, 2011
Author(s)
Chad R. Snyder, Dean M. DeLongchamp, Jessica S. Henry
The impact of regioregularity in poly(3-hexylthiophene-2,5-diyl) (P3HT) on crystallization behavior and quantitative limits to possible crystal sizes is discussed, and it is explained why regioregularities must be reported for any study to be properly

Spin Dependent Charge Pumping in SiC Metal-Oxide-Semiconductor Field-Effect-Transistors

August 25, 2011
Author(s)
Brad Bittel, Patrick Lenahan, Jason Ryan, Jody Fronheiser, Aivars Lelis
We demonstrate a very powerful electrically detected magnetic resonance (EDMR) technique, spin dependent charge pumping (SDCP) and apply it to 4H SiC metal-oxide-semiconductor field-effect-transistors (MOSFETs). SDCP combines a widely used electrical

Design and Optimization of a Permeation Testing System for Polymer Coatings

August 8, 2011
Author(s)
Adrian E. Verwolf
Measurements of liquid permeation through freestanding Parylene C membranes were made using a high- performance testing system, which demonstrated fast response (≤ 30 seconds) to changing concentrations in the sweep gas stream and detectability of less

A Simple Series Resistance Extraction Methodology for Advanced CMOS Devices

August 1, 2011
Author(s)
Jason P. Campbell, Kin P. Cheung, John S. Suehle, A Oates
Series resistance has become a serious obstacle inhibiting the performance of advanced CMOS devices. However, series resistance quantification in these same advanced CMOS devices is becoming exceedingly difficult. In this study, we demonstrate a very

Characterization of the non-uniform reaction in chemically-amplified calix[4]resorcinarene molecular resist thin films

July 19, 2011
Author(s)
Vivek M. Prabhu, Shuhui Kang, Regis J. Kline, Dean M. DeLongchamp, Daniel A. Fischer, Wen-Li Wu, Sushil K. Satija, Jing Sha, Christopher K. Ober, Peter V. Bonnesen
The ccc stereoisomer-purified tert-butoxycarbonyloxy (t-Boc) protected calix[4]resorcinarene molecular resists blended with photoacid generator exhibit a non-uniform photoacid catalyzed reaction in thin films. The surface displays a reduced reaction extent

The Effect of Folding on the Mechanical Properties and Internal Structures of Fibers Used in Ballistic Applications

July 18, 2011
Author(s)
Haruki Kobayashi, Walter G. McDonough, Hae-Jeong Lee, Jae H. Kim, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
The failure of a first responder's soft body armor (SBA) composed of poly (p-phenylene benzobisoxazole) (PBO) fibers has prompted researchers to assess the long-term durability and effectiveness of current and future SBA products. Based on existing data
