First and Second Order Raman Spectroscopy of Monoclinic
Benjamin M. Janzen, Roland Gillen, Zbigniew Galazka +2
We employ a combined experimental-theoretical study of the first- and second-order Raman modes of monoclinic -GaO. The investigated materials is of particular intere…
Interlayer excitonic spectra of vertically stacked MoSe/WSe heterobilayers
Roland Gillen
The optical spectra of vertically stacked MoSe/WSe heterostructures contain additional 'interlayer' excitonic peaks that are absent in the individual monolayer materials an…
Hybridized intervalley moiré excitons and flat bands in twisted WSe bilayers
Samuel Brem, Kai-Qiang Lin, Roland Gillen +4
The large surface-to-volume ratio in atomically thin 2D materials allows to efficiently tune their properties through modifications of their environment. Artificial stacking of two…
Two-Dimensional Antimony Oxide
Stefan Wolff, Roland Gillen, Mhamed Assebban +2
Two-dimensional (2D) antimony, so-called antimonene, can form antimonene oxide when exposed to air. We present different types of single- and few-layer antimony oxide structures, b…
Vibrational signatures of diamondoid dimers with large intramolecular London dispersion interactions
Christoph Tyborski, Tobias Hueckstaedt, Roland Gillen +5
We analyze the vibrational properties of diamondoid compounds via Raman spectroscopy. The compounds are interconnected with carbon-carbon single bonds that exhibit exceptionally la…
Phonon dispersion of MoS
Hans Tornatzky, Roland Gillen, Hiroshi Uchiyama +1
Transition metal dichalcogenides like MoS, MoSe, WS, and WSe have attracted enormous interest during recent years. They are van-der-Waals crystals with highly aniso…
