Ballistic Electron Emission Microscopy on CoSi/Si(111) interfaces: band structure induced atomic-scale resolution and role of localized surface states
K. Reuter, F. J. Garcia-Vidal, P. L. de Andres +2
Applying a Keldysh Green`s function method it is shown that hot electrons injected from a STM-tip into a CoSi/Si(111) system form a highly focused beam due to the silicide ba…
LEED Holography applied to a complex superstructure: a direct view of the adatom cluster on SiC(111)-(3x3)
K. Reuter, J. Schardt, J. Bernhardt +3
For the example of the SiC(111)-(3x3) reconstruction we show that a holographic interpretation of discrete Low Energy Electron Diffraction (LEED) spot intensities arising from orde…
Quantum mechanical analysis of the elastic propagation of electrons in the Au/Si system: application to Ballistic Electron Emission Microscopy
K. Reuter, P. L. de Andres, F. J. Garcia-Vidal +3
We present a Green's function approach based on a LCAO scheme to compute the elastic propagation of electrons injected from a STM tip into a metallic film. The obtained 2D current…
Extending holographic LEED to ordered small unit cell superstructures
K. Reuter, J. A. Vamvakas, D. K. Saldin +5
Following on the success of the recent application of holographic LEED to the determination of the 3D atomic geometry of Si adatoms on a SiC(111) p(3x3) surface, which enabled that…
