MoO3 Films for Efficient Hole-Injection in Organic Electronics
J. Meyer, R. Khalandovsky, P. Görrn and A. Kahn, Princeton Universiy
Transition-metal
oxides
(TMO), such as molybdenum tri-oxide (MoO3), are promising
hole-injection electrode materials for organic electronics because of their
large work function and high conductivity. They are superior to the widely used
organic polymer PEDOT:PSS which causes device degradation. However, deposition
of MoO3 layers
from high-temperature sources is problematical for flexible organic-based
electronics.

Topological Surface States Penetrate Through Surface Barriers
J. Seo, P. Roushan, H. Beidenkopf, Y. S. Hor, R. J. Cava, and A. Yazdani, Princeton University
Topological surface states are a new class of novel electronic states that are potentially useful for quantum computing or spintronicapplications. Unlike conventional two-dimensional electron states, these surface states are expected to be immune to localization and to overcome barriers caused by material imperfection. Previous experiments have demonstrated that topological surface states do not backscatter between equal and opposite momentum states, due to their chiralspin texture.

See how they run... electrons on the surface of a novel insulator
Dong-Xia Qu, Y. S. Hor, Jun Xiong, R. J. Cava and N. P. Ong, Princeton University
Novel electronic applications often result from fresh theoretical insights into long-familiar materials. Recently, strong interest has focused on the “topological insulators”, notably Bi2Se3and Bi2Te3. In these solids, the electrons on the surface display highly unusual properties. For example, they travel like massless particles (photons and neutrinos), and are much less susceptible to scattering by lattice imperfections. To date, much of the information on topological insulators has come from photoemission experiments and scanning tunneling microscopy.
