Emergence of hidden phases of methylammonium lead-iodide (CH${}_3$NH${}_3$PbI${}_3$) upon compression

José A. Flores-Livas, Daniele Tomerini, Maximilian Amsler +3

We perform a thorough structural search with the minima hopping method (MHM) to explore low-energy structures of methylammonium lead iodide. By combining the MHM with a forcefield,…
