Time evolution of SAED patterns for MAPbI₃ films which are not exposed to the atmosphere (using an air-free transfer holder). (a–d) SAED pattern matches the [315] zone axis in tetragonal MAPbI₃. Twin peaks are observed as marked by white circles. (e) Time evolution of the rotationally averaged SAED pattern for MAPbI₃ observed in TEM for samples which are not exposed to air (using an air-free transfer holder). The dose rate is ∼5.58 eÅ^–2 s^–1.
