HIGHLIGHTS
- who: Seyeong Cha from the (UNIVERSITY) have published the Article: Order-disorder phase transition driven by interlayer sliding in lead iodides, in the Journal: (JOURNAL) of 15/Nov/2022
- what: The authors report the discovery of a phase transition whose mechanism is identified as interlayer sliding in lead iodides, a layered material widely used to synthesize lead halide perovskites. The authors first clarify that the low-temperature structure of PbI2 is not the 2H polytype as known before, but 4H polytype shown in Fig 1c. The authors report the discovery of order-disorder phase transitions . . .
