Sonication-assisted liquid phase exfoliation of two-dimensional CrTe under inert conditions
Kevin Synnatschke, Narine Moses Badlyan, Angelika Wrzesińska +8
Liquid phase exfoliation (LPE) has been used for the successful fabrication of nanosheets from a large number of van der Waals materials. While this allows to study fundamental cha…
Electronic Properties and Interlayer Interactions in Antimony Oxide Homo- and Heterobilayers
Stefan Wolff, Roland Gillen, Janina Maultzsch
Antimony shows promise as a two-dimensional (2D) mono-elemental crystal, referred to as antimonene. When exposed to ambient conditions, antimonene layers react with oxygen, forming…
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…
Isotopic study of Raman active phonon modes in -GaO
Benjamin M. Janzen, Piero Mazzolini, Roland Gillen +5
Holding promising applications in power electronics, the wide band gap material gallium oxide has emerged as a vital alternative to materials like GaN and SiC. The detailed study o…
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…
