Spontaneous bidirectional ordering of CH(3)NH(3)(+) in lead iodide perovskites at room temperature: The origins of the tetragonal phase

CH(3)NH(3)PbI(3) is a hybrid organic-inorganic material with a perovskite structure and a temperature-dependent polymorphism whose origins are still unclear. Here we perform ab initio molecular dynamics simulations in order to investigate the structural properties and atom dynamics of CH(3)NH(3)PbI(...
