Abstract

In this reply, we address the concerns that were raised about our paper on CsPbBr₃ single crystals. M. Szafrański criticized the dielectric and DSC data in our original paper claiming that they were affected by the experimental artefacts or poor quality of the investigated single crystals, as his DSC and dielectric data did not show any low temperature anomalies in CsPbBr₃. We argue in this reply that our main conclusions were not made based on the DSC and dielectric experiments. Here, we emphasize the importance of other experiments like EPR and XRD that were performed to understand if there are any structural transformations of CsPbBr₃ at low temperatures. We believe that M. Szafrański did not take into account all the discussion that was presented in our original paper. We hope to clear the doubts in this reply.
