    • Nonhydrogenic exciton spectrum in perovskite CH3 NH3 PbI3 
      Menéndez Proupin, Eduardo; Beltrán Ríos, Carlos L.; Wahnón, P. (Wiley & Sons, 2015)
      The excitons in the orthorhombic phase of the perovskite CH3NH3PbI3 are studied using the effective mass approximation. The electron-hole interaction is screened by a distance-dependent dielectric function, as described ...
    • Self-consistent relativistic band structure of the CH3NH3PbI3 perovskite 
      Menéndez Proupin, Eduardo; Palacios, P.; Wahnón, P.; Conesa, J. C. (American Physical Society, 2014)
      The electronic structure and properties of the orthorhombic phase of the CH3NH3PbI3 perovskite are computed with density functional theory. The structure, optimized using a van der Waals functional, reproduces closely the ...
