Anatase phase dominated TiO2 nanoplates were deposited on p-Si by Radio-Frequency magnetron sputtering technique. Metal-TiO2 nanoplates-Metal (M-TN-M) planer electrodes were fabricated using various metal electrodes such as Al, Ag, Ni, and Au. Temperature dependent current-voltage (I-V) characteristics of M-TN-M devices were measured in air and 1% hydrogen atmosphere. Barrier height between metal and TiO2 nanoplates is decreased in presence of hydrogen as compared to air and increases with temperature. The sensing response of the device is strongly dependent on the alteration of barrier height and operating temperature. The relative response was observed similar to 46% for Ohmic Al electrodes. The effective barrier heights were measured to be similar to 0.15 eV for Ag, similar to 0.17 eV for Ni and similar to 0.19 eV for Au electrodes at 175 degrees C and corresponding change in relative response were measured similar to 49%, similar to 58%, and similar to 77%, respectively. Response and recovery times for highest sensitivity device (Au-TN-Au) were found to be similar to 7 and 114 s respectively at 175 degrees C operating temperature.
