Abstract

Read online

2D layered materials attract interest due to their potential for application in nanoelectronics and optoelectronics. Here authors report an order-disorder-type phase transition driven by temperature in bulk lead iodides, and interlayer sliding is identified to play a key role in the mechanism of this phase transition.
