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…
Engineering correlated Dirac fermions and flat bands on SiC with transition-metal adatom lattices
Henri Menke, Niklas Enderlein, Yi-Ting Tseng +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…
