A simple and robust approach to reducing contact resistance in organic devices

December 3, 2018
Author(s)
Lamport Zachary, Katrina Barth, Hyunsu Lee, Martin Guthold, Iain McCulloch, John E. Anthony, Lee J. Richter, Eliot Gann, Dean DeLongchamp, Oana Jurchescu
Efficient injection of charge carriers from the contacts into the semiconductor layer is crucial for achieving high-performance organic devices. The potential drop necessary to accomplish this process yields a resistance associated with the contacts

Electronic Properties and Structure of Single Crystal Perylene

Sujitra J. Pookpanratana, Katelyn Goetz, Emily G. Bittle, Hamna Haneef, Lin You, Christina A. Hacker, Steven W. Robey, Oana Jurchescu, Ruslan Ovsyannikov, Erika Giangrisostomi
The transport properties of electronic devices made from single crystalline molecular semiconductors outperform those composed of thin-films. To further understand the superiority of these extrinsic properties, an understanding of the intrinsic electronic

Blade Coating Aligned, High-Performance, Semiconducting-Polymer Transistors

February 22, 2018
Author(s)
Lee J. Richter, Hyun W. Ro, Regis J. Kline, Daniel A. Fischer, Dean M. DeLongchamp, Lars Thomsen, Christopher McNeil, Dawei Wu, Maria Kaplan, Eliot H. Gann
Recent demonstration of mobilities in excess of 10 cm2V-1s-1 have energized research in solution deposition of polymers for thin film transistor applications. Due to the lamella motif of most soluble, semiconducting polymers, the local mobility is

Synchrotron Methods for Flexible Hybrid Electronics Industrial Recommendations on Interagency (DoC-DoD-DoE) Partnerships to Address Measurement Challenges Hindering the Flexible Hybrid Electronics Manufacturing Ecosystem

February 12, 2018
Author(s)
Christopher L. Soles, Richard A. Vaia, Ronald Pindak
The round-table participants concluded that facilities at NSLS-II provide immediate opportunities to address some of the critical processing and measurement challenges that are blocking the path towards a sustainable US-centric Flexible Hybrid Electronic

Ferroelectricity in Polar Polymer-based FETs: A Hysteresis Analysis

January 15, 2018
Author(s)
Vasileia Georgiou, Dmitry Veksler, Jason Campbell, Jason Ryan, Pragya Shrestha, D. E. Ioannou, Kin P. Cheung
There is an increasing number of reports on polar polymer-based Ferroelectric Field Effect Transistors (FeFETs), where the hysteresis of the drain current - gate voltage (Id-Vg) curve is investigated as the result of the ferroelectric polarization effect

Interface Engineering for Nanoelectronics

August 16, 2017
Author(s)
Christina A. Hacker, Robert C. Bruce, Sujitra J. Pookpanratana
Innovation in the electronics industry is tied to interface engineering as devices increasingly incorporate new materials and shrink. Molecular layers offer a versatile means of tuning interfacial electronic, chemical, physical, and magnetic properties

Reduced Bimolecular Recombination in Blade-Coated, High-Efficiency, Small-Molecule Solar Cells
