The band structures at near the R point of all-inorganic cubic CsSnBr3 perovskite nanoplatelets (NPLs) are investigated by using an 8-band k·p method. The Luttinger parameters are given by fitting the first-principles results, the E-K curves and optical transition rule at near the R point are obtain...
