Abstract:	We studied the structural properties of ZnO nanostructures with x-ray absorption fine structure (XAFS) to understand the growth mechanism of vertically aligned ZnO nanorods of the average diameter of 50 - 150 nm. The orientation-dependent XAFS measurements parallel and perpendicular to the c-axis of ZnO nanorods with lengths of 0.1, 0.2 and 1.0 microns showed different amount of disorder existing in the bond lengths. The disorder in ab-plane was greatly reduced, as the ZnO formed into nanorods. We also demonstrate that the lateral surface of the ZnO nanorods have oxygen-termination determined by the XAFS analysis.
