Nonparabolic dispersion of charge carriers in CsPbI${}_3$ in the orthorhombic phase

O. S. Sultanov, D. K. Loginov, I. V. Ignatiev +3

The dispersion curves for the electrons and holes in CsPbI${}_3$ in the orthorhombic phase are calculated using the density functional theory (DFT), with the spin-orbit coupling take…
