When Cubic Is Not Isotropic: Phonon-Exciton Decoupling in CuInSnS Single Crystals
Lara Kim Linke, Yvonne Tomm, Xinyun Liu +9
Atomic-scale disorder can create hidden optical anisotropy even in crystals that are structurally cubic on average. Here, we show that CuInSnS single crystals host locally symm…
Halide Perovskites as Spin-1 Dirac Materials
Dmitry Marchenko, Maryam Sajedi, Maxim Krivenkov +8
Halide perovskites are a promising class of materials for optoelectronic and photovoltaic applications, exhibiting high power conversion efficiency due to strong light absorption a…
Temperature-dependent EXAFS measurements of the Pb L3-edge allow quantification of the anharmonicity of the lead-halide bond of chlorine-substituted methylammonium (MA) lead triiodide
Götz Schuck, Daniel M. Többens, Dirk Wallacher +3
This article reports on studies of chlorine-substituted MAPbI3 using combined temperature-dependent XRD synchrotron and Pb-L3 edge EXAFS to analyze the anharmonicity of the lead ha…
Infrared Spectroscopic Study of Vibrational Modes across the Orthorhombic-Tetragonal Phase Transition in Methylammonium Lead Halide Single Crystals
Götz Schuck, Daniel M. Többens, Monika Koch-Müller +2
Single crystals of the methylammonium (MA) lead halides MAPbI3, MAPbBr3, and MAPbCl3 have been investigated using infrared spectroscopy with the aim of analyzing structural and dyn…
