Energy Shift and Wavefunction Overlap of Metal-Organic Interface-States
M. Marks, N. L. Zaitsev, B. Schmidt +6
The properties of Shockley-type interface states between -conjugated organic molecular layers and metal surfaces are investigated by time-resolved two-photon photoemission exper…
Inelastic decay rate of quasiparticles in a two-dimensional spin-orbit coupled electron system
I. A. Nechaev, P. M. Echenique, E. V. Chulkov
We present a study of the inelastic decay rate of quasiparticles in a two-dimensional electron gas with spin-orbit interaction. The study is done within the G0W0 approximation. The…
Theoretical study of ionization of an alkali atom adsorbed on a metal surface by laser assisted subfemtosecond pulse
A. K. Kazansky, P. M. Echenique
The first numerical simulation of the process of ionization of an atom adsorbed on a metal surface by the subfemtosecond pulse is presented. The streaking scheme is considered, whe…
One-dimensional model of streaking experiment in solids
A. K. Kazansky, P. M. Echenique
One-dimensional model for study of sub--femtosecond experiment with metal surface is put forward. The important features of the system, such as the pseudopotential for electron mot…
Point-like spin-dependent interaction in calculations of self-energy ladder diagrams
I. A. Nechaev, I. Nagy, P. M. Echenique +1
An instantaneous and zero-range spin-dependent interaction, derived by summing an infinite number of electron-hole ladder diagrams within a local approximation, is analyzed as a fu…
Experimental time-resolved photoemission and ab initio study of lifetimes of excited electrons in Mo and Rh
A. Mönnich, J. Lange, M. Bauer +5
We have studied the relaxation dynamics of optically excited electrons in molybdenum and rhodium by means of time resolved two-photon photoemission spectroscopy (TR-2PPE) and ab in…
Strong spin-orbit splitting on Bi surfaces
Yu. M. Koroteev, G. Bihlmayer, J. E. Gayone +4
Using first-principles calculations and angle-resolved photoemission, we show that the spin-orbit interaction leads to a strong splitting of the surface state bands on low-index su…
