Buildup and dephasing of Floquet-Bloch bands on subcycle time scales
S. Ito, M. Schüler, M. Meierhofer +10
Strong light fields have created spectacular opportunities to tailor novel functionalities of solids. Floquet-Bloch states can form under periodic driving of electrons and enable e…
Ultrafast electron dynamics in a topological surface state observed in two-dimensional momentum space
J. Reimann, K. Sumida, M. Kakoki +5
We study ultrafast population dynamics in the topological surface state of SbTe in two-dimensional momentum space with time- and angle-resolved two-photon photoemission. Li…
Second-harmonic generation as probe for structural and electronic properties of buried GaP/Si(001) interfaces
K. Brixius, A. Beyer, J. Güdde +4
Optical second-harmonic generation is demonstrated to be a sensitive probe of the buried interface between the lattice matched semiconductors gallium phosphide and silicon with (00…
Model potential for the description of metal/organic interface states
N. Armbrust, F. Schiller, J. Güdde +1
We present an analytical one-dimensional model potential for the description of electronic interface states that form at the interface between a metal surface and flat-lying adlaye…
Formation of image-potential states at the graphene/metal interface
N. Armbrust, J. Güdde, U. Höfer
The formation of image-potential states at the interface between a graphene layer and a metal surface is studied by means of model calculations. An analytical one-dimensional model…
