| Title: Band structure and optical properties of cubic CsSnBr3 perovskite nanoplatelets | |
| Abstract: Here we will review our recent work on the all-inorganic lead-free cubic CsSnBr3 perovskite band structure simulation.We report a new simple 8-band k.p method to calculate the band structure and optical properties of cubic CsSnBr3bulk perovskite and their nanoplatelets (NPLs).The bulk inversion asymmetry is taken into consideration in our model. The band splitting caused by the bulk inversion asymmetry is observed at non-R point. The optical transition rule follows the Δn=0 for the thin NPLs, however, for the thicker NPLs, the optical transition rule of Δn=0 does not hold. The results are helpful to understand the cubic perovskite based spintronics and optoelectronics. Acknowledgements: W.J.
