Fig. 5: Comparison of measured and calculated ε2.
From: Dual phases of crystalline and electronic structures in the nanocrystalline perovskite CsPbBr3
a The x, y, and z components of ε2 calculated from the tetragonal and orthorhombic band structures. b Comparison of the combined tetragonal and orthorhombic ∈2 in different ratios with the data at 7, 100, 150, and 300 K. The results are offset by 0.1 unit for clarity. c The percentage of orthorhombic nanocrystals as a function of temperature.
