Abstract

ZnO Nanorods Array Heterostructure Growth By Hydrothermal Method: By two step hydrothermal method,  ZnO nanorod arrays heterostructure can be synthesized.To prepare nanorods array,  first step of hydrothermal method is controlled in low concentration. Second step will be controlled in a high concentration condition, and it can create second morphology other than nanorods array.The main precursors used in this paper are zinc acetate dehydrate (Zn(OAc)2．2H2O) and hexamethylenetetramine (HMTA).Through SEM images and the growth condition,  an idea of structure-forming mechanism is introduced.
