Magnon-mediated terahertz spin transport in metallic Gd|Pt stacks
Oliver Gueckstock, Tim Amrhein, Beatrice Andres +11
We study femtosecond spin transport in a Gd|Pt stack induced by a laser pulse. Remarkably, the dynamics of the spin current from Gd to Pt suggests that its dominant driving force i…
Ultrafast Optical Control of Rashba Interactions in a TMDC Heterostructure
Henry Mittenzwey, Abhijeet Kumar, Raghav Dhingra +6
We investigate spin relaxation dynamics of interlayer excitons in a MoSe2/MoS2 heterostructure induced by the Rashba effect. In such a system, Rashba interactions arise from an out…
Local work-function manipulation by external optical stimulation
Jan Böhnke, Beatrice Andres, Larissa Boie +4
Strongly differing static dipole moments of the trans and cis isomers of photochromic azobenzene allow for optical switching the work function of azobenzene-functionalized self-ass…
Strain fingerprinting of exciton valley character
Abhijeet Kumar, Denis Yagodkin, Roberto Rosati +13
Momentum-indirect excitons composed of electrons and holes in different valleys define optoelectronic properties of many semiconductors, but are challenging to detect due to their…
Probing the formation of dark interlayer excitons via ultrafast photocurrent
Denis Yagodkin, Elias Ankerhold, Abhijeet Kumar +5
Optically dark excitons determine a wide range of properties of photoexcited semiconductors yet are hard to access via conventional spectroscopies. Here, we develop a time-resolved…
Spin/valley coupled dynamics of electrons and holes at the interface
Abhijeet Kumar, Denis Yagodkin, Nele Stetzuhn +6
The coupled spin and valley degrees of freedom in transition metal dichalcogenides (TMDs) are considered a promising platform for information processing. Here, we use a TMD heteros…
