Simulation of spin-polarized scanning tunneling microscopy on complex magnetic surfaces: The case of a Cr monolayer on Ag(111)
spin-polarized scanning tunneling complex magnetic surfaces Cr monolayer Ag
2011/8/17
Abstract: We propose an atom-superposition-based method for simulating spin-polarized scanning tunneling microscopy (SP-STM) from first principles. Our approach provides bias dependent STM images in h...
Streaking and Wigner time delays in photoemission from atoms and surfaces
Streaking Wigner photoemission atoms and surfaces
2011/9/13
Streaked photoemission metrology allows the observation of an apparent relative time delay between the detection of photoelectrons from different initial electronic states. This relative delay is obta...

The thermal behavior of the (010), (110) and (111) copper surfaces is studied by molecular dynamics simulation. We have used a many-body potential based on the tight-binding model in order to describe...
