Transparent conducting properties of SrSnO₃ and ZnSnO₃

Optical and electronic properties of orthorhombic and trigonal AXO3 (A=Cd, Zn; X=Sn, Ge): First principle calculation

“…We have summarized the band gap energies for ZnXO 3 and CdXO 3 in Table 1 with the available theoretical and experimental results. Our results in perovskite type orthorhombic structures can roughly compare with band structure for SrSnO 3 and CaGeO 3 compound in same structure [8,25]. The band structures of CdXO 3 and ZnXO 3 is qualitatively similar to that of SrSnO 3 and CaGeO 3 .…”

“…The band structures of CdXO 3 and ZnXO 3 is qualitatively similar to that of SrSnO 3 and CaGeO 3 . The band gap for SrSnO 3 (2.9 eV) [8] is higher than that for CdXO 3 and ZnXO 3 compounds. The real e 1 (v) and imaginary e 2 (v) parts of e(v) D e 1 (v) -ie 2 (v) were calculated by using Kramers-Kroning transformation [28].…”

“…However, until now little attention has been paid to oxides containing only main group cations with such electronic configuration, so these compounds gave us a new strategy to search more polar crystals [6]. To search for new high performance ferroelectrics based on the above strategy we have investigated CdXO 3 and ZnXO 3 (XHGe, Sn), because the investigation of perovskiteand ilmenite-based oxide systems with ferroelectric properties has gained large interest within the scientific community in recent years [7,8]. It is well known that LiNbO 3 compounds is so important optical materials with a wide applications in optoelectronics and other nonlinear systems.…”

Sn(II)-Containing Phosphates as Optoelectronic Materials

“…These were done based on first principles DFT calculations combined with the particle swarm optimization algorithm as implemented in the CALYPSO code [36,37]. We also particularly calculated the optical absorption spectra of the compounds when doped [38][39][40]. This is an important but often neglected aspect for identifying transparent conductors.…”

Structure and optical band gaps of (Ba,Sr)SnO3 films grown by molecular beam epitaxy

“…6,7 SrSnO 3 , which is orthorhombic (Pbnm space group 8 ) is believed to either possess a direct gap (valence band maximum at C) 7 or the two band gaps are very close in energy. 9 The reported experimental band gap values for BaSnO 3 and SrSnO 3 range between 2.9 and 4.0 eV (Refs. 2, 7, and 10-13) and 4.1 eV to 4.27 eV, 7,10 respectively.…”
