Physical Properties of ZnO: Al Nanorods for Piezoelectric Nanogenerator Application

In this paper, we explore the electromechanical, optical, and luminescent properties of aluminum doped zinc oxide (ZnO) nanorods. The design of aqueous solution growth ZnO nanorods with an aluminum doped zinc oxide nanostructure is discussed, and electrical, optoelectronic, and mechanical properties of the obtained nanorods are described. The results show that the dopant concentration affects nanorod growth and thus the size of the ZnO: Al nanorods. The resistivity decreases with increasing substrate temperature, and the dopant concentration become a positive electricity transition to negative electricity positively correlated. The piezoelectric characteristics of a nanogenerator system fabricated with the nanorods are also discussed.
