“…26,28 The agreement of a VBM of Γ + 3 also settled the symmetry assignment of the Sn s-derived conduction-band minimum (CBM) as Γ + 1 , as suggested by experimental arguments 13,14,29 and calculations. 9,11 The experimental results largely agree that the lowest dipole-allowed direct (direct-allowed) transition features a strong polarization anisotropy, but the origin of this transition is heavily debated. Experimental 10 as well as theoretical [7][8][9]11 reports are plagued by inconsistencies in the ordering and relative energies of the lower-lying VB states.…”

“…9,11 The experimental results largely agree that the lowest dipole-allowed direct (direct-allowed) transition features a strong polarization anisotropy, but the origin of this transition is heavily debated. Experimental 10 as well as theoretical [7][8][9]11 reports are plagued by inconsistencies in the ordering and relative energies of the lower-lying VB states. Nagasawa and Shionoya reported an allowed transition value of 3.75 eV for light polarized perpendicular to the tetragonal c axis (E ⊥ c), which they associated with a VB of symmetry Γ − 5 lying 0.15 to 0.20 eV below the VBM.…”

“…Despite the vast experimental and theoretical literature on SnO 2 , many discrepancies and unsolved issues remain. These include details of the valence-band (VB) ordering and band symmetries, 7-10 the role of indirect transitions, 9,11,12 and the exciton spectrum. 10,[13][14][15] Although SnO 2 is widely used for its optical properties, its dielectric function is not available in the literature.…”

The structural, electronic, and optical properties of the semiconducting oxide SnO 2 are investigated using first-principles calculations. We employ the G 0 W 0 formalism based on hybrid-functional calculations to compute the quasiparticle band structure and density of states for which we find good agreement with results from photoemission and two-photon absorption experiments. We also address open questions regarding the band ordering and band symmetries. In a second step we use our electronic structure as a starting point to calculate optical spectra by solving the Bethe-Salpeter equation including the electron-hole interaction. The dielectric tensor is predicted for a wide range of photon energies. Our results resolve the long-standing discrepancy between theory and experiment on the highly anisotropic onsets of absorption. The anisotropy can be explained in terms of dipole-allowed direct transitions in the vicinity of the valence-band maximum without having to invoke lower lying valence bands.

“…The SnO 2 lm is a transparent conductive coating material and a n-type semiconductor with a wide band gap (approximately 3.7 eV) [1] and tetragonal rutile structure. The SnO 2 lm shows the best thermal and chemical stability, it is inexpensive, and it has good adhesion to most of the substrates, however it has a high resistivity.…”

In this study, the reversible capacities, as well as the cycling behavior, of crystalline antimony-doped tin oxide (ATO) lms have been investigated. ATO lms were deposited on Cr-coated stainless steel substrates by the RF magnetron sputtering technique, with antimony-doped tin oxide (SnO2:Sb) target in a mixed oxygen/argon gas environment. The ATO lms were deposited for 1.0 h in a mixture of Ar and O2 environment with O2/Ar ratio of 10/90, at sputtering power of 75 W, 100 W and 125 W RF. ATO lms were examined by X-ray diraction (XRD), eld emission scanning electron microscopy (FESEM). The electrochemical properties of ATO anodes were studied using 2016-type coin cells assembled in an argon-lled glove box.

In this work, antimony doped tin oxide (SnO2:Sb) thin lms were fabricated using a radio frequency magnetron sputtering system on Si wafer and glass substrates. The base pressure in the sputtering chamber was 1.0 Pa. The SnO2:Sb thin lms were deposited for 1.0 h in a mixture of Ar and O2 environment with O2/Ar ratio of 10/90 at 75, 100, and 125 W RF sputtering powers. The microstructure of SnO2:Sb thin lms was assessed using a eld emission scanning electron microscopy. The crystallographic structure of the sample was determined by X-ray diraction. The average surface roughness (Ra) was measured with atomic force microscopy. The electrical resistivity of the deposited lms was measured by the four-point-probe method. The thicknesses of the lms were measured by surface proler.
