Epitaxial growth and magnetic phase transitions in non-centrosymmetric EuPdSi thin films
Sebastian Kölsch, Alfons G. Schuck, Olena Fedchenko +9
Non-centrosymmetric magnetic materials are a promising platform for stabilizing chiral spin textures, such as skyrmions and cycloidal magnetic states. This is particularly true in…
Momentum-space Observation of Optically Excited Non-Thermal Electrons in Graphene with Persistent Pseudospin Polarization
Jin Bakalis, Sergii Chernov, Ziling Li +11
The unique optical properties of graphene, with broadband absorption and ultrafast response, make it a critical component of optoelectronic and spintronic devices. Using time-resol…
Active Sites of Te-hyperdoped Silicon by Hard X-ray Photoelectron Spectroscopy
Moritz Hoesch, Olena Fedchenko, Mao Wang +10
Multiple dopant configurations of Te impurities in close vicinity in silicon are investigated using photoelectron spectroscopy, photoelectron diffraction, and Bloch wave calculatio…
Clamping effect on temperature-induced valence transition in epitaxial EuPdSi thin films grown on MgO(001)
Sebastian Kölsch, Alfons Schuck, Olena Fedchenko +10
Bulk EuPdSi show a temperature-driven valence transisition of europium from +2 above 200 K to +3 below 100 K, which is correlated with a shrinking by approximat…
Momentum-Resolved Exciton Coupling and Valley Polarization Dynamics in Monolayer WS
Alice Kunin, Sergey Chernov, Jin Bakalis +8
Coupling between exciton states across the Brillouin zone in monolayer transition metal dichalcogenides can lead to ultrafast valley depolarization. Using time- and angle-resolved…
Vectorial spin-polarization detection in multichannel spin-resolved photoemission spectroscopy using an Ir(001) imaging spin filter
Erik D. Schaefer, Stephan Borek, Jürgen Braun +5
We report on spin- and angular resolved photoemission spectroscopy using a high-resolution imaging spin filter based on a large Ir(001) crystal enhancing the effective figure of me…
Determination of surface and interface magnetic properties for the multiferroic heterostructure Co/BaTiO3 using SPLEED and ARPES
St. Borek, J. Braun, J. Minar +4
Co/BaTiO(001) is one of the most interesting multiferroic heterostructures as it combines different ferroic phases, setting this way the fundamentals for innovative technical a…
Condensation of holes into antiferromagnetic droplets in the organic semiconductor (DOEO)[HgBr]TCE
O. V. Koplak, A. Chernenkaya, K. Medjanik +6
Changes of the electronic structure accompanied by charge localization and a transition to an antiferromagnetic ground state were observed in the (DOEO)[HgBr]TCE organic se…
A new charge-transfer complex in UHV co-deposited tetramethoxypyrene and tetracyanoquinodimethane
K. Medjanik, S. Perkert, S. Naghavi +11
UHV-deposited films of the mixed phase of tetramethoxypyrene and tetracyanoquinodimethane (TMP1-TCNQ1) on gold have been studied using ultraviolet photoelectron spectroscopy (UPS),…
