Polarization-Dependent Raman Selection Rules in SbS from First Principles and Experiment
Tobias Dierke, Michael Hüttenkofer, Stefan Wolff +4
Antimony sulfide (SbS) is a semiconductor composed of quasi-one-dimensional ribbon-like structural units, which give rise to pronounced structural anisotropy in the bulk cr…
Unravelling the oxygen influence in cubic bixbyite InO on Raman active phonon modes by isotope studies
Johannes Feldl, Roland Gillen, Janina Maultzsch +5
In this study, we performed comprehensive investigations on the Raman active phonon modes in cubic bixbyite InO, an important oxide based, wide-bandgap semiconductor. Funda…
Semimetallic two-dimensional defective graphene networks with periodic 4-8 defect lines
Roland Gillen, Janina Maultzsch
We present theoretical simulations of the electronic properties of graphene-like two-dimensional (2D) carbon networks with a periodic arrangement of defect lines formed by alternat…
Cove-edged Chiral Graphene Nanoribbons with Chirality-Dependent Bandgap and Carrier Mobility
K. Liu, W. Zheng, S. Osella +13
Graphene nanoribbons (GNRs) have garnered significant interest due to their highly customizable physicochemical properties and potential utility in nanoelectronics. Besides control…
Correlative and in situ microscopy investigation of phase transformation, crystal growth and degradation of antimony sulfide thin films
Mingjian Wu, Maïssa K. S. Barr, Vanessa M. Koch +8
Antimony sulfide (SbS), a compound of earth-abundant elements with highly anisotropic, quasi-layered crystal structure, triggered growing interest as a solar absorber in ph…
Identification of Polytypism and Their Dislocations in Bilayer MoS2 Using Correlative Transmission Electron Microscopy and Raman Spectroscopy
Xin Zhou, Tobias Dierke, Mingjian Wu +7
Stacking orders and topological defects substantially influence the physical properties of 2D van der Waals (vdW) materials. However, the inherent features of 2D materials challeng…
Production of Ultra-Thin and High-Quality Nanosheet Networks via Layer-by-Layer Assembly at Liquid-Liquid Interfaces
Joseph Neilson, Eoin Caffrey, Oran Cassidy +10
Solution-processable 2D materials are promising candidates for a range of printed electronics applications. Yet maximising their potential requires solution-phase processing of nan…
Engineering correlated Dirac fermions and flat bands on SiC with transition-metal adatom lattices
Henri Menke, Niklas Enderlein, Roland Gillen +5
We propose three transition-metal adatom systems on SiC surfaces as a versatile platform to realize massless Dirac fermions and flat bands with strong electronic correlations. Usin…
Interlayer Raman modes in twisted bilayer TMDCs
Eileen Schneider, Kenji Watanabe, Takashi Taniguchi +1
Twisted bilayer two-dimensional transition-metal dichalgocenides (TMDCs) exhibit a range of novel phenomena such as the formation of moiré excitons and strongly correlated phases.…
Moiré lattice of twisted bilayer graphene as template for non-covalent functionalization
Tobias Dierke, Stefan Wolff, Roland Gillen +7
We present a novel approach to achieve spatial variations in the degree of non-covalent functionalization of twisted bilayer graphene (tBLG). The tBLG with twist angles varying bet…
Hybrid moiré excitons and trions in twisted MoTe-MoSe heterobilayers
Shen Zhao, Xin Huang, Roland Gillen +8
We report experimental and theoretical studies of MoTe-MoSe heterobilayers with rigid moiré superlattices controlled by the twist angle. Using an effective continuum model…
Family behavior and Dirac bands in armchair nanoribbons with 4-8 defect lines
Roland Gillen, Janina Maultzsch
Bottom-up synthesis from molecular precursors is a powerful route for the creation of novel synthetic carbon-based low-dimensional materials, such as planar carbon lattices. The we…
Molecular beam growth of graphene on mica
Gunther Lippert, Jarek Dabrowski, Yuji Yamamoto +5
We demonstrate molecular beam growth of graphene on biotite mica substrates at temperatures below 1000°C. As indicated by optical and atomic force microscopy, evaporation of carbon…
