In this work we have studied the NO2 sensing properties of the sensors with tetrapods. The tetrapods that were used in the production were obtained by CVD route, and their structural analysis was carried out using SEM, XRD and EDX methods. The sensors were produced by a different method that the one mentioned in our another work, and additional electrical I-V characterization was carried out. As well...
Titanium dioxide (TiO_2) thin films were prepared by spin coating technique of sol precursor on Corning 7059 glass substrates. Spectral transmittances of as deposited and annealed samples were measured in the range of 250 to 1100 nm. Optical band gaps were calculated from the Tauc plots and was found to be about 3.78 eV for the annealed samples at 500°C. X-ray diffraction patterns were performed with...
