Webt -- Goldschmidt tolerance factor. In an ideal cubic perovskite crystalline structure the A-site and B-site cations optimize their equilibrium bond distances to the oxygen elements without inducing any distortion of the unit cell at t = 1. When 0.78 < t < 1.05, a distorted perovskite structure can normally be stabilized. WebNov 1, 2024 · Since the electronegativity increases with the decrease in the cation size and the tolerance factor is more approaching 1 for the smaller halide ions in CsPbX 3 perovskite, the gradually decreased doping amount with the decrease in the cation size should be attributed to the increased size mismatch between doping X-ions and host I-ions.
