Verification of ultrafast spin transfer effects in FeNi alloys
Christina Möller, Henrike Probst, G. S. Matthijs Jansen +7
The optical intersite spin transfer (OISTR) effect was recently verified in FeNi using magneto-optical Kerr measurements in the extreme ultraviolet range. However, on…
Unraveling Femtosecond Spin and Charge Dynamics with EUV T-MOKE Spectroscopy
Henrike Probst, Christina Möller, Maren Schumacher +7
The magneto-optical Kerr effect (MOKE) in the extreme ultraviolet (EUV) regime has helped to elucidate some of the key processes that lead to the manipulation of magnetism on ultra…
Ultrafast nano-imaging of dark excitons
David Schmitt, Jan Philipp Bange, Wiebke Bennecke +15
The role and impact of spatial heterogeneity in two-dimensional quantum materials represents one of the major research quests regarding the future application of these materials in…
Direct visualization of hybrid excitons in van der Waals heterostructures
Giuseppe Meneghini, Marcel Reutzel, Stefan Mathias +2
Van der Waals heterostructures show fascinating physics including trapped moire exciton states, anomalous moire exciton transport, generalized Wigner crystals, etc. Bilayers of tra…
Ultrafast dynamics of bright and dark excitons in monolayer WSe and heterobilayer WSe/MoS
Jan Philipp Bange, Paul Werner, David Schmitt +15
The energy landscape of optical excitations in mono- and few-layer transition metal dichalcogenides (TMDs) is dominated by optically bright and dark excitons. These excitons can be…
Probing correlations in the exciton landscape of a moiré heterostructure
Jan Philipp Bange, David Schmitt, Wiebke Bennecke +13
Excitons are two-particle correlated bound states that are formed due to Coulomb interaction between single-particle holes and electrons. In the solid-state, cooperative interactio…
Multiorbital exciton formation in an organic semiconductor
Wiebke Bennecke, Andreas Windischbacher, David Schmitt +13
Harnessing the optoelectronic response of organic semiconductors requires a thorough understanding of the fundamental light-matter interaction that is dominated by the excitation o…
