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…

Mechanochemical Synthesis of the Lead-Free Double Perovskite Cs2[AgIn]Br6 and its Optical Properties
Joachim Breternitz, Sergiu Levcenko, Hannes Hempel +4
Hitting hard on the binary halides yields in the formation of Cs2[AgIn]Br6. The lead-free double perovskite marks, although not usable itself, a further step forward in finding sus…
