Comment on "Dynamic range of nanotube- and nanowire-based electromechanical systems"
Christoph Stampfer, Stefan Rotter, Joachim Burgdoerfer
We investigate the role of quantum effects (e.g. zero-point energy fluctuations) in the physics of nanotube- and nanowire-based electromechanical sensors as discussed in a recent a…
Imaging Spin Reorientation Transitions in Consecutive Atomic Co layers
Farid El Gabaly, Silvia Gallego, Carmen Munoz +6
By means of spin-polarized low-energy electron microscopy (SPLEEM) we show that the magnetic easy-axis of one to three atomic-layer thick cobalt films on ruthenium crystals changes…
Spin-polarized surface states close to adatoms on Cu(111)
B. Lazarovits, L. Szunyogh, P. Weinberger
We present a theoretical study of surface states close to 3d transition metal adatoms (Cr, Mn, Fe, Co, Ni and Cu) on a Cu(111) surface in terms of an embedding technique using the…
Structural and Electronic Properties of the Interface between the High-k oxide LaAlO3 and Si(001)
Clemens J. Foerst, Karlheinz Schwarz, Peter E. Bloechl
The structural and electronic properties of the LaAlO3/Si(001) interface are determined using state-of-the-art electronic structure calculations. The atomic structure differs from…
Ab-initio simulations on growth and interface properties of epitaxial oxides on silicon
Clemens J. Foerst, Christopher R. Ashman, Karlheinz Schwarz +1
The replacement of SiO2 by so-called high-k oxides is one of the major challenges for the semiconductor industry to date. Based on electronic structure calculations and ab-initio m…
Differential probability for surface and volume electronic excitations in Fe, Pd and Pt
Wolfgang S. M. Werner
The normalized differential mean free path for volume scattering and the differential surface excitation probability for medium energy electrons travelling in Fe, Pd and Pt are ext…
