Momentum-resolved observation of exciton formation dynamics in monolayer WS
Robert Wallauer, Raul Perea-Causin, Lasse Münster +8
The dynamics of exciton formation in transition metal dichalcogenides is difficult to measure experimentally, since many momentum-indirect exciton states are not accessible to opti…
Observation of enhanced chiral asymmetries in the inner-shell photoionization of uniaxially oriented methyloxirane enantiomers
Maurice Tia, Martin Pitzer, Gregor Kastirke +38
Most large molecules are chiral in their structure: they exist as two enantiomers, which are mirror images of each other. Whereas the rovibronic sublevels of two enantiomers are al…
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.…
Spin Mapping of Surface and Bulk Rashba States in Ferroelectric a-GeTe(111) Films
H. J. Elmers, R. Wallauer, M. Liebmann +16
A comprehensive mapping of the spin polarization of the electronic bands in ferroelectric a-GeTe(111) films has been performed using a time-of-flight momentum microscope equipped w…
ARPES sensitivity to short-range antiferromagnetic correlations
R. Wallauer, S. Sanna, E. Lahoud +2
Angle-resolved photoemission spectroscopy (ARPES) is one of most powerful techniques to unravel the electronic properties of layered materials and in the last decades it has lead t…
Interatomic-Coulombic-decay-induced recapture of photoelectrons in helium dimers
P. Burzynski, F. Trinter, J. B. Williams +17
We investigate the onset of photoionization shakeup induced interatomic Coulombic decay (ICD) in He2 at the He+*(n = 2) threshold by detecting two He+ ions in coincidence. We find…
