We present 3D imaging of several types of Au superlattices by Z-contrast STEM electron tomography. A series of tilted Z-contrast STEM images consisting of 60 images were collected by using the Hitachi HD-2300 STEM. The alignment and 3D reconstruction were performed to reconstruct 3D volume of the nanoparticles superlattices. By electron tomography the 3D structure of the superlattices can be directly viewed and more useful information can be revealed.
