Intramolecular Exciton Transport in Conjugated Polymers
David Blank (IRG-2)
Using a series of acceptor-polymer-acceptor triads, IRG-2 investigators have measured intramolecular exciton diffusion in poly-3(hexylthiophene) (P3HT) for the first time.

Magnetic Charge Crystallization in Artificial Spin Ice
Chris Leighton (IRG-3), in collaboration with the Univ. of Illinois, Penn State, and Los Alamos
“Artificial spin ice” is a term used for arrays of nanoscale magnetic islands on lattices that geometrically frustrate inter-island interactions.

Ligand-free Colloids and Surface Doping of Silicon Nanocrystals
Uwe Kortshagen
Inks of inorganic nanocrystals hold great promise for printed electronics but the widely used organic surfactants (ligands) needed to stabilize these inks degrade the electrical quality of the printed films.

Kondo Physics at Ferromagnet/Normal Metal Interfaces
P. A. Crowell and C. Leighton
The idealized picture of an interface between two elemental materials is simply an abrupt transition between planes containing two different types of atoms.

Enhanced Refractive Index Sensing with Monodisperse Faceted Plasmonic Nanoparticles
Yu Jin Shin, Emilie Ringe, Michelle L. Personick, M. Fernanda Cardinal, Chad A. Mirkin, Laurence D. Marks, Richard P. Van Duyne, and Mark C. Hersam
The shape-dependent optical properties of metal
nanostructures have motivated efforts to correlate
nanoparticle structure with plasmonic behavior. In
particular, gold bipyramids (BPs) are of interest due
to their sharp tips that lead to strong localized field
enhancement and high sensitivity to the surrounding
environment. However, despite their potential,
relatively few reports have studied the optical
properties of sub-100 nm BPs due to their relatively
low synthetic yields. To overcome this issue, density
