  • Carbon-dioxide as annealing atmosphere to retain the electrical properties of indium-tin oxide 
    Mayandi, Jeyanthinath; Finstad, Terje; Venkatesan, Ragavendran; Vajeeston, Ponniah; Karazhanov, Smagul; Venkatachalapathy, Vishnukanthan (Journal article / Tidsskriftartikkel / SubmittedVersion, 2020)
    In practical applications of indium-tin-oxide (ITO) annealing at temperatures ~400 °C without degrading its electrical and optical properties is an important challenge. In the present work, commercial Indium-tin oxide (ITO) ...
  • Comparative analysis of electronic structure and optical properties of crystalline and amorphous silicon nitrides 
    Karazhanov, Smagul; Kroll, P; Holt, A; Bentzen, A; Ulyashin, Alexander (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)
    We present a study of the electronic structure and optical properties of Si3N4 and Si2N3H in crystalline and amorphous phases by first-principles calculations. We find that besides structural disorder those matrix atoms ...
  • Electronic structure and optical properties of ZnSiO3 and Zn2SiO4 
    Karazhanov, Smagul; Ravindran, Ponniah; Fjellvåg, Helmer; Svensson, Bengt Gunnar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)
    The electronic structure and optical properties of orthorhombic, monoclinic, and rhombohedral (corundum type) modifications of ZnSiO3, and of rhombohedral, tetragonal, and cubic (spinel type) modifications of Zn2SiO4 have ...
