Modified Low-Temperature Scanning Tunneling Microscope for Ultrafast Pump-Probe Spectroscopy
Vibhuti N. Rai, Junyoung Sim, Nils Bogdanoff +7
Combining scanning tunneling microscopy (STM) with terahertz pulses (THz-STM) enables ultrafast dynamics of phonons, spins, and charge carriers to be probed with atomic-scale spati…
Influence of atomic-scale defects on coherent phonon excitations by THz near fields in an STM
Vibhuti N. Rai, Junyoung Sim, Florian Faaber +7
Coherent phonons describe the collective, ultrafast motion of atoms and play a central role in light-induced structural dynamics. Here, we employ terahertz scanning tunneling micro…
Electronic and magnetic properties of single chalcogen vacancies in MoS/Au(111)
Sergey Trishin, Christian Lotze, Nils Krane +1
Two-dimensional (2D) transition-metal dichalcogenides (TMDC) are considered highly promising platforms for next-generation optoelectronic devices. Owing to its atomically thin stru…
Variations of vibronic states in densely-packed structures of molecules with intramolecular dipoles
Sergey Trishin, Christian Lotze, Johanna Richter +5
Electrostatic potentials strongly affect molecular energy levels and charge states, providing the fascinating opportunity of molecular gating. Their influence on molecular vibratio…
Tuning a two-impurity Kondo system by a moiré superstructure
Sergey Trishin, Christian Lotze, Friedemann Lohss +4
Two-impurity Kondo models are paradigmatic for correlated spin-fermion systems. Working with Mn atoms on Au(111) covered by a monolayer of MoS, we tune the inter-adatom exchang…
Resolution of intramolecular dipoles and push-back effect of individual molecules on a metal surface
Sergey Trishin, Tobias Müller, Daniela Rolf +5
Molecules consisting of a donor and an acceptor moiety can exhibit large intrinsic dipole moments. Upon deposition on a metal surface, the dipole may be effectively screened and th…
Moiré tuning of spin excitations: Individual Fe atoms on MoS/Au(111)
Sergey Trishin, Christian Lotze, Nils Bogdanoff +2
Magnetic adatoms on surfaces are exchange coupled to their environment, inducing fast relaxation of excited spin states and decoherence. These interactions can be suppressed by ins…
