Fracture strength and Young's modulus of ZnO nanowires
S. Hoffmann, F. Ostlund, J. Michler +4
The fracture strength of ZnO nanowires vertically grown on sapphire substrates was measured in tensile and bending experiments. Nanowires with diameters between 60 and 310 nm and a…
Exchange interaction between single magnetic adatoms
P. Wahl, P. Simon, L. Diekhoener +4
The magnetic coupling between single Co atoms adsorbed on a copper surface is determined by probing the Kondo resonance using low-temperature scanning tunneling spectroscopy. The K…
Transmission of correlated electrons through sharp domain walls in magnetic nanowires: a renormalization group approach
M. A. N. Araujo, V. K. Dugaev, V. R. Vieira +2
The transmission of correlated electrons through a domain wall in a ferromagnetic one dimensional system is studied theoretically in the limit of a domain wall width smaller or com…
Single-particle states in spherical Si/SiO quantum dots
A. S. Moskalenko, J. Berakdar, A. A. Prokofiev +1
We calculate ground and excited electron and hole levels in spherical Si quantum dots inside SiO in a multiband effective mass approximation. Luttinger Hamiltonian is used for…
Revivals, collapses and magnetic-pulse generation in quantum rings
A. S. Moskalenko, A. Matos-Abiague, J. Berakdar
Using a microscopic theory based on the density matrix formalism we investigate quantum revivals and collapses of the charge polarization and charge current dynamics in mesoscopic…
Effect of short-range order on the electronic structure and optical properties of the CuZn alloy : an augmented space approach
Kartick Tarafder, Atisdipankar Chakrabarti, Kamal Krishna Saha +1
In this work we have combined the generalized augmented space method introduced by one of us with the recursion method of Haydock et al (GASR), within the framework of the local de…
