| Outline of Final Research Achievements |
In this research, we investigated fundamental challenges of chemical sensors based on nanoscale metal oxides, which are promising devices to electrically discriminate volatile molecules in ambient. Long-term stability of nanoscale metal oxide device properties, which is one of the most important requirements of these sensors, was intensively investigated via fabricating/evaluating metal oxide nanowire devices. By controlling surface or interface properties of the nanoscale metal oxides, the long-term stability of the electrical properties and sensor response of metal oxide nanowire devices were significantly improved.
