Resonant Raman signatures of bright and momentum-dark exciton coupled by intervalley phonon scattering in monolayer WSe2
Hendrik Lambers, Nihit Saigal, Lara Blinov +3
Exciton-phonon coupling in atomically thin transition metal dichalcogenides governs key processes such as exciton thermalization and intervalley scattering and remains challenging…
GHz non-reciprocal optical conductivity in hematite (-)
Peng Rao, Johannes Gröbmeyer, P. Peter Stavropoulos +5
We study the non-reciprocal properties of the iron oxide -FeO (hematite) in the canted easy-plane antiferromagnetic phase, specifically in the GHz to THz frequency rang…
Electrically and optically active charge carrier traps in silicon-doped few-layer GaSe
M. Bissolo, R. Li, M. Ogura +9
Understanding defects in atomically thin van der Waals (vdW) semiconductors is essential for advancing their use in next-generation optoelectronic and photovoltaic devices. Here, w…
High-Energy Interlayer Exciton Ensembles in MoSe/WSe Heterostructures by Laguerre-Gaussian Excitation
Mirco Troue, Johannes Figueiredo, Gabriel Mittermair +7
We reveal the higher energetic luminescence part of interlayer exciton ensembles in MoSe/WSe heterostructures upon excitation by an optical Laguerre-Gaussian mode. The exci…
Carrier-envelope phase control of ultrafast photocurrents in layered MoS
Johannes Schmuck, Björn Sinz, Nina Pettinger +2
We demonstrate carrier-envelope-phase (CEP)-controlled photocurrents in mono-, bi-, and tri-layer MoS driven by few-cycle laser pulses. The photocurrent in the two-terminal dev…
