Abstract
  • Well-oriented thin films of methyl-ammonium trihalogenostannates CH3NH3SnX3 compounds (X=Cl,Br) are grown by the single source thermal ablation technique. Optical absorption and structural analysis of CH3NH3SnX3 thin films are combined with ab initio calculations in order to clarify their electronic properties and the role of the organic cation. The structural calculations reproduce well the measured lattice parameters, and optical measurements reveal a direct gap absorption onset for both compounds, in agreement with the calculated band structures. It turns out from projected density of states analysis that the valence and conduction bands take negligible contribution from the methylammonium. It is inferred that the band gap mainly depends on the ionicity and size of the inorganic cage SnX3. (literal)
