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…
Magnetic phase transition in CoO confined to a vycor type porous glass. Neutron diffraction study
I. V. Golosovsky, I. Mirebeau, G. André +4
Neutron diffraction studies of antiferromagnetic CoO confined to a vycor type porous glass demonstrate a continuous magnetic phase transition with a decreased Néel temperature and…
