We investigate the theoretical band structure of organic–inorganic perovskites APbX3 with tetragonal crystal structure. Using D4h point group symmetry properties, we derive a general 16-band Hamilt...

International audience; Since their first synthesis in 2015, the all-inorganic lead halide perovskite nanocrystals CsPbX3(X=Cl,Br,I) have attracted a great deal of attention due to their outstanding electronic and optical properties as well as their
