چکیده
A new transparent conducting oxide ~TCO!, which can be expressed as Ga32xIn51xSn2O16; 0.2 <x<1.6, has been identified. The equilibrium phase relationships of this new material with respect to three other TCOs in Ga2O3–In2O3–SnO2 are reported. The optical properties of this phase are slightly superior to Sn-doped indium oxide ~ITO! and depend on composition. A room-temperature conductivity of 375 V cm was obtained for H2-reduced Ga2.4In5.6Sn2O16 . This value is an order of magnitude lower than commercial ITO films, but comparable to values reported for bulk, polycrystalline Sn-doped In2O3. © 1997 American Institute of Physics. @S0003-6951~97!03513-4#

متن کاملSynthesis of Low-Melting Metal Oxide and Sulfide Nanowires and Nanobelts
The bulk nucleation and basal growth of semiconducting nanowires from molten Ga pools has been demonstrated earlier using oxygen/hydrogen plasma over molten Ga pools. Herein, we extend the above concept for bulk synthesis of oxide and sulfide nanowires of low-melting metal melts such as Sn and In. Specifically, nanowires of b-Ga2O3, b-In2O3, SnO2, a-Ga2S3, and b-In2S3 were synthesized using dir...
متن کاملSynthesis and Characterization of Highly Transparent and Conductive SnO2:F and In2O3:Sn thin Films Deposited by Spray Pyrolysis
Highly transparent and conductive thin films of SnO2:F and In2O3:Sn (ITO) have been prepared on glass substrates using the simple pyrolitic (spray) method. Through an exhaustive parameter study and using as diagnostic method for the film quality a figure of merit defined as a function of both, the transmittance and the electric resistivity, the conditions to prepare the SnO2:F and ITO films, wi...

Subsolidus phase relationships in the Ga2O3–SnO2–ZnO system were determined at 1250 ◦C using solid state synthesis and X-ray powder diffraction. The two spinels, Zn2SnO4 and ZnGa2O4, formed a complete solid solution. The optical band gap of the spinel varied with composition from 3.6 eV (Zn2SnO4) to 4.7 eV (ZnGa2O4). All samples were white and insulating except those containing Ga-doped ZnO. Th...
متن کاملBethe-Salpeter calculation of optical-absorption spectra of In2O3 and Ga2O3
Transparent conducting oxides keep attracting strong scientific interest not only due to their promising potential for “transparent electronics” applications but also due to their intriguing optical absorption characteristics. Materials such as In2O3 and Ga2O3 have complicated unit cells and, consequently, are interesting systems for studying the physics of excitons and anisotropy of optical ab...
