Intervalley scattering in MoS imaged by two-photon photoemission with a high-harmonic probe
Robert Wallauer, Johannes Reimann, Nico Armbrust +2
We report on the direct mapping of electron transfer in the momentum space of bulk MoS by means of time- and angle-resolved two-photon photoemission with a high-harmonic probe.…

Spectroscopy and Dynamics of a Two-Dimensional Electron Gas on top of Ultrathin Helium Films on Cu(111)
Nico Armbrust, Jens Güdde, Ulrich Höfer +2
Electrons in image-potential states on the surface of bulk helium represent a unique model system of a two-dimensional electron gas. Here, we investigate their properties in the ex…
