1. Vertically Segregated Structure and Properties of small molecule-polymer blend semiconductors for organic thin film transistors
Published: 8/27/2012
Authors: Nayool Shin, Dean M DeLongchamp, Jihoon Kang, Regis J Kline, Lee J Richter, Vivek M Prabhu, Balaji Purushothamanc, John E Anthony, Do Y Yoon
Abstract: The phase-segregated structure and the electrical properties of thin film blends of the small-molecule semiconductor fluorinated 5,11-bis(triethylsilylethynyl) anthradithiophene with insulating binder polymers were studied for organic thin film trans ...

2. A synchrotron beamline for extreme-ultraviolet photoresist testing
Published: 9/30/2011
Authors: Charles S. Tarrio, Steven Grantham, Shannon Bradley Hill, Nadir Sabirovich Faradzhev, Lee J Richter, Chester Knurek, Thomas B Lucatorto
Abstract: Before being used in an extreme-ultraviolet (EUV) scanner, photoresists must first be evaluated for sensitivity and tested to ensure that they will not contaminate the scanner optics. The new NIST facility described here provides data on the contami ...

4. The NIST EUV facility for advanced photoresist qualification using the witness-sample test
Published: 8/29/2011
Authors: Steven Grantham, Charles S. Tarrio, Shannon Bradley Hill, Lee J Richter, Thomas B Lucatorto, J. van Dijk, C. Kaya, N. Harned, R. Hoefnagels, M. Silova, J. Steinhoff
Abstract: Before being used in an extreme-ultraviolet (EUV) scanner, photoresists must first be qualified to ensure that they will not excessively contaminate the scanner optics or other parts of the vacuum environment of the scanner. At the National Institute ...

6. Conduction and Loss Mechanisms in Flexible Oxide-Based Memristors
Published: 3/21/2011
Authors: Joseph Leo Tedesco, Nadine Gergel-Hackett, Laurie Stephey, Andrew A Herzing, Madelaine Herminia Hernandez, Christina Ann Hacker, Jan Obrzut, Lee J Richter, Curt A Richter
Abstract: In order to study the conduction and loss mechanisms behind their operation, flexible sol-gel based memristors were fabricated with differing oxide film thicknesses and device sizes. XPS, TEM, EELS, and VASE measurements indicated the oxide was amor ...

9. Origin of Nanoscale Variations in Photoresponse of an Organic Solar Cell
Published: 4/22/2010
Authors: Behrang H Hamadani, Suyong S. Jung, Paul M Haney, Lee J Richter, Nikolai B Zhitenev
Abstract: Photo generated charge transport in bulk heterojunction (BHJ) solar cells is strongly dependent on the active layer nanomorphology resulting from phase segregation and connectivity of the donor and acceptor regions. Scanning probe-based techniques an ...
