Description: We report calculations of the electronic structure and optical properties of doped n -type perovskite BaSnO 3 and layered perovskites. While doped BaSnO 3 retains its transparency for energies below the valence to conduction band onset, the doped layered compounds exhibit below band edge optical conductivity due to transitions from the lowest conduction band. This gives absorption in the visible for Ba 2 SnO 4 . Thus, it is important to minimize this phase in transparent conducting oxide (TCO) films. Ba 3 Sn 2 O 7 and Ba 4 Sn 3 O 10 have strong transitions only in the red and infrared, respectively. Thus, there may be opportunities for using these as wavelength filtering TCO.
