Topological Protection Against Backscattering
P. Roushan, J. Seo, C. V. Parker, Y.-S. Hor, D. Hsieh, D Qian, A. Richardella, M. Z. Hasan, R. J. Cava and A. Yazdani (Princeton University)
Topological insulators are a new class of insulators in which a bulk gap for electronic excitations is generated by strong spin-orbit coupling.

CMU MRSEC Hosts over 60 scientists at the 1st Summer School on 3D Microstructure Studies
On June 1st -4th, 2010, CMU hosted 67 scientists from around the world
at the 1st Summer School on 3D Microstructure Studies. MRSEC Faculty,
graduate students and researchers introduced the techniques that were
developed and continue to be developed here at CMU to characterize of
the internal structure of polycrystalline materials. The school
consisted of a mix of lectures, demonstrations and hands-on interactive
activities for the participants. Sections were taught on measuring the

Virus-grown battery materials
Angela Belcher, Gerbrand Ceder (MIT)
Widely used in small electronic devices and in the nascent market for
HEVS (Hybrid Electric Vehicles), lithium ion batteries store more energy
for theirweight, operate at a higher voltage, and hold a charge much
longer thanother rechargeable batteries. As a new approach, Belcher and
Ceder of the MIT MRSEC IRG-I have explored a biological way to create
new charge storage materials for lithium ion batteries by using a virus
as a scaffold totemplate the growth and assembly of nanoscale electrode

Standing Plasmon Waves on Ag Grating Structures
S.H. Guo, D. Britti, J.J Heetderks, H.C. Kan and R. J. Phaneuf
Surface plasmons are light-energy propagating electromagnetic modes trapped at the interface between certain metals (notably gold and silver) and a dielectric. They are also of interest for optical processes enhanced by strong local electric fields.

Antiferroelectric Phase in Sm Doped BiFeO3
I. Takeuchi
We have identified a composition in Sm doped BiFeO3 which exhibits a complex mixture of ferroelectric phase and an antiferroelectric phase. Left shows a high resolution TEM image of a region displaying an interface between a rhombohedral ferroelectric phase (FE matrix) and antiferroelectric (antipolar clusters).

Poking Holes in Graphene Makes it Magnetic
Jian‐Hao Chen, W. G. , Cullen, E. D. Williams, M. S. Fuhrer
Magnetism is
typically associated with “transition metal” elements such as nickel or iron,
from the middle of the periodic table.
These elements contain d electrons which are localized on the atoms, and have a
“spin” or magnetic moment. Carbon
contains no d
electrons and is not normally magnetic.
