Mechanism for puddle formation in graphene
Shaffique Adam, Suyong Jung, Nikolai N. Klimov +3
When graphene is close to charge neutrality, its energy landscape is highly inhomogeneous, forming a sea of electron-like and hole-like puddles, which determine the properties of g…
Magnetization dynamics induced by in-plane currents in ultrathin magnetic nanostructures
Kyoung-Whan Kim, Soo-Man Seo, Jisu Ryu +2
Ultrathin magnetic systems have properties qualitatively different from their thicker counterparts, implying that different physics governs their properties. We demonstrate that va…
On the magnetization textures in NiPd nanostructures
Jean-Yves Chauleau, Benjamin McMorran, Rachid Belkhou +8
We have observed peculiar magnetization textures in NiPd nanostructures using three different imaging techniques: magnetic force microscopy, photoemission electron mi…
Surface conduction of topological Dirac electrons in bulk insulating Bi2Se3
Dohun Kim, Sungjae Cho, Nicholas P. Butch +5
The newly-discovered three-dimensional strong topological insulators (STIs) exhibit topologically-protected Dirac surface states. While the STI surface state has been studied spect…
Organic photovoltaic bulk heterojunctions with spatially varying composition
Paul M. Haney
Models of organic bulk heterojunction photovoltaics which include the effect of spatially varying composition of donor/acceptor materials are developed and analyzed. Analytic expre…
Microscopic Polarization in Bilayer Graphene
Gregory M. Rutter, Suyong Jung, Nikolai N. Klimov +3
Bilayer graphene has drawn significant attention due to the opening of a band gap in its low energy electronic spectrum, which offers a promising route to electronic applications.…
