Structural details of Al/Al2O3 junctions and their role in formation of electron tunnel barriers
M. Koberidze, M. J. Puska, R. M. Nieminen
We present a computational study of the adhesive and structural properties of the Al/Al2O3 interfaces as building blocks of the Metal-Insulator-Metal (MIM) tunnel devices, where el…
Characterization of aluminum oxide tunnel barriers by combining transport measurements and transmission electron microscope imaging
T. Aref, A. Averin, S. van Dijken +7
We present two approaches for studying the uniformity of a tunnel barrier. The first approach is based on measuring single-electron and two-electron tunneling in a hybrid single-el…
Magnetic Impurity Affected by Spin-Orbit Coupling: Behavior near a Topological Phase Transition
F. M. Hu, T. O. Wehling, J. E. Gubernatis +2
We investigate the effect of spin-orbit coupling on the behavior of magnetic impurity at the edge of a zigzag graphene ribbon by means of quantum Monte Carlo simulations. A peculia…
High-pressure neutron study of the morphotropic PZT: phase transitions in a two-phase system
J. Frantti, Y. Fujioka, J. Zhang +6
In piezoelectric ceramics the changes in the phase stabilities versus stress and temperature in the vicinity of the phase boundary play a central role. The present study was dedica…
Behavior of a Magnetic Impurity in Graphene in the Presence of a Vacancy
F. M. Hu, J. E. Gubernatis, Hai-Qing Lin +2
With quantum Monte Carlo methods, we investigate the consequences of placing a magnetic adatom adjacent to a vacancy in a graphene sheet. We find that instead of the adatom propert…
Electronic Transport Properties of Carbon NanoBuds
J. A. Furst, J. Hashemi, T. Markussen +3
Fullerene functionalized carbon nanotubes -- NanoBuds -- form a novel class of hybrid carbon materials, which possesses many advantageous properties as compared to the pristine com…
