Abstract
In this study, Al doped ZnO(Al:ZnO) nanorods were synthesized on the conductive ITO glass substrate using hydrothermal method, and its piezoresistive properties were measured. Electrical impedance of the Al:ZnO nanorods have decreased compared to the undoped nanorods. However, the shape of the nanorod became more slender and inclined to the substrate if more than 1% aluminum ion was mixed to the reactive solution. Piezoresistive change ratio of the Al:ZnO nanorods was almost the same with undoped sample, which agrees with the results of Ga doped ZnO nanorods in our previous study.
