TL;DR: It is observed that glycol side chain percentages of >50% are required to achieve volumetric charging, while lower glycol chain percentages show a mixed operation with high required voltages to allow for bulk charging of the organic semiconductor.
Journal ArticleDOI
A simple and robust approach to reducing contact resistance in organic transistors
Zachary A. Lamport,Katrina J. Barth,Hyunsu Lee,Eliot Gann,Sebastian Engmann,Hu Chen,Martin Guthold,Iain McCulloch,Iain McCulloch,John E. Anthony,Lee J. Richter,Dean M. DeLongchamp,Oana D. Jurchescu +12 more
TL;DR: A simple and efficient strategy for reducing the contact resistance in organic thin-film transistors by creating high work function domains at the surface of the injecting electrodes to promote channels of enhanced injection is demonstrated.
Journal ArticleDOI
Balancing Charge Storage and Mobility in an Oligo(Ether) Functionalized Dioxythiophene Copolymer for Organic- and Aqueous- Based Electrochemical Devices and Transistors.
Lisa R. Savagian,Anna M. Österholm,James F. Ponder,Katrina J. Barth,Jonathan Rivnay,John R. Reynolds +5 more
TL;DR: A demonstration of how a single ProDOT-based polymer, prepared using benign polymerization chemistry and functionalized with highly polar side chains, can be used to access a range of highly desirable properties and performance metrics relevant to electrochemical, optical, and bioelectronic applications is provided.
Journal ArticleDOI

TL;DR: In this paper, the synthesis and electrical properties of nine new alkylated silane self-assembled monolayers (SAMs) were reported, and they were examined in a metal/insulator/metal configuration, with a highly-doped silicon bottom contact and a eutectic gallium-indium liquid metal top contact.
Journal Article
Fluorinated benzalkylsilane molecular rectifiers
Zachary A. Lamport,Angela D. Broadnax,David G. Harrison,Katrina J. Barth,Lee Mendenhall,Clayton T. Hamilton,Martin Guthold,Mark E. Welker,Oana D. Jurchescu,Timo Thonhauser +9 more
TL;DR: It is found that the rectification ratio correlates positively with the strength of the molecular dipole moment and it is reduced with increasing molecular length.
