Localized basis sets for unbound electrons in nanoelectronics
D. Soriano, D. Jacob, J. J. Palacios
It is shown how unbound electron wave functions can be expanded in a suitably chosen localized basis sets for any desired range of energies. In particular, we focus on the use of g…
Spin transport in nanocontacts and nanowires
David Jacob
In this thesis we study electron transport through magnetic nanocontacts and nanowires with ab initio quantum transport calculations. The aim is to gain a thorough understanding of…
Anisotropic magnetoresistance in nanocontacts
D. Jacob, J. Fernandez-Rossier, J. J. Palacios
We present ab initio calculations of the evolution of anisotropic magnetoresistance (AMR) in Ni nanocontacts from the ballistic to the tunnel regime. We find an extraordinary enhan…
Magnetic and orbital blocking in Ni nanocontacts
David Jacob, J. Fernández-Rossier, J. J. Palacios
We address the fundamental question of whether magneto-resistance (MR) of atomic-sized contacts of Nickel is very large because of the formation of a domain wall (DW) at the neck.…
Charge-localization and isospin-blockade in vertical double quantum dots
David Jacob, Bernhard Wunsch, Daniela Pfannkuche
Charge localization seems unlikely to occur in two vertically coupled symmetric quantum dots even if a small bias voltage breaks the exact isospin-symmetry of the system. However f…
