Channeling of a sub-angstrom electron beam in a crystal mapped to two-dimensional molecular orbitals
Robert Hovden, Huolin L. Xin, David A. Muller
The propagation of high-energy electrons in crystals is in general a complicated multiple scattering problem. However, along high-symmetry zone axes the problem can be mapped to th…
Graphene as a reversible spin manipulator of molecular magnets
Sumanta Bhandary, Saurabh Ghosh, Heike Herper +3
One of the primary objectives in molecular nano-spintronics is to manipulate the spin states of organic molecules with a d-electron center, by suitable external means. In this lett…
The Magnetoelectric Effect in Transition Metal Oxides: Insights and the Rational Design of New Materials from First Principles
Turan Birol, Nicole A. Benedek, Hena Das +6
The search for materials displaying a large magnetoelectric effect has occupied researchers for many decades. The rewards could include not only advanced electronics technologies,…
Reversible Control of Magnetic Interactions by Electric Field in a Single Phase Material
P. J. Ryan, J. -W. Kim, T. Birol +9
Intrinsic magnetoelectric coupling describes the interaction between magnetic and electric polarization through an inherent microscopic mechanism in a single phase material. This p…
Self-compensation in highly n-type InN
C. Rauch, F. Tuomisto, P. D. C. King +3
Acceptor-type defects in highly n-type InN are probed using positron annihilation spectroscopy. Results are compared to Hall effect measurements and calculated electron mobilities.…
Magnetodielectric coupling and phonon properties of compressively strained EuTiO3 thin films deposited on LSAT
S. Kamba, V. Goian, M. Orlita +13
Compressively strained epitaxial (001) EuTiO3 thin films of tetragonal symmetry have been deposited on (001) (LaAlO3)_0.29-(SrAl_{1/2}Ta_{1/2}O3)_0.71 (LSAT) substrates by reactive…
