Metallization: New Metallic Ordered Phase of Perovskite CsPbI3 under Pressure (Adv. Sci. 14/2019)

In article number 1900399, Xiaoli Huang, Fubo Tian, Tian Cui, and co-workers track the bandgap evolution of perovskite CsPbI3 under pressure by a diamond anvil cell (DAC) device. The application of pressure reduces interatomic distances and profoundly modifies electronic orbitals and bonding patterns. Finally, a new metallic ordered phase of perovskite CsPbI3 is obtained at 39.3 GPa.
