Neodymium (Nd)-doped SnO_2 transparent conducting oxide thin films were prepared by vapour deposition technique under different deposition parameters: substrate temperature, time and flow rate of vapour deposition, amount of base material, distance between the substrate and spray gun tip, and dopant (Nd) concentration. The structural, optical, electrical and photo-electronic properties of the doped and undoped SnO_2 films were studied. X-ray diffraction studies shows the polycrystalline nature of the films with preferential orientation along the (101), (211) and (301) planes and an average grain size of 100 Å. The optical properties of these films were studied by measuring their optical transmission …

Phosphate glasses with various compositions of lithium oxide and indium oxide were synthesized by melt quenching technique. The glass forming ability parameter K_{gl} was characterized by differential thermal analysis. The electrical measurements for all the glass samples were carried out in the frequency range of 10 Hz to 10^{6} Hz and at a temperature range of 393-513 K by the Impedance spectroscopy. Frequency dependent conductivity follows the power law. The ac conductivity increases with temperature following the Arrhenius law. Master curve in the scaling analysis suggesting the temperature independent conduction relaxation mechanism.
