Journal ArticleDOI
Phosphonic Acid-Modified Barium Titanate Polymer Nanocomposites with High Permittivity and Dielectric Strength
Philseok Kim,Simon C. Jones,Peter J. Hotchkiss,Joshua N. Haddock,Bernard Kippelen,Seth R. Marder,Joseph W. Perry +6 more
TL;DR: In this article, a set of ligands, each bearing an aliphatic octyl chain with a different terminal binding group, was used to modify the surface of barium titanate (BT) nanoparticles.
Journal ArticleDOI
Switchable electro-optic diffractive lens with high efficiency for ophthalmic applications
Guoqiang Li,David L. Mathine,Pouria Valley,Pekka Ayras,Joshua N. Haddock,M. S. Giridhar,Gregory A. Williby,Jim Schwiegerling,Gerald Meredith,Bernard Kippelen,Seppo Honkanen,Nasser Peyghambarian +11 more
TL;DR: Previously undescribed switchable, flat, liquid-crystal diffractive lenses that can adaptively change their focusing power have the potential of revolutionizing the field of presbyopia correction when combined with automatic adjustable focusing power.
Journal ArticleDOI
A comprehensive study of short channel effects in organic field-effect transistors
TL;DR: In this paper, the authors present a comprehensive study of short channel effects in organic field-effect transistors by measuring the electrical characteristics of devices with fixed channel width and varying channel length, and show that drain-source currents from transistors with a channel length of 50μm show excellent agreement with the square law equations derived for crystalline Si MOSFETs in both the linear and saturation regimes.
Journal ArticleDOI
Photo-Patternable Hole-Transport Polymers for Organic Light-Emitting Diodes
Benoit Domercq,Richard D. Hreha,Yadong Zhang,Nathalie Larribeau,Joshua N. Haddock,Christopher Schultz,Seth R. Marder,Bernard Kippelen +7 more
TL;DR: In this article, a series of soluble arylamine-based hole transporting polymers with various ionization potentials have been synthesized, which allows substitution of aryl groups on the amine with electron-withdrawing and electron-donating moieties which permits tuning of the redox potential of the polymer.
