Abstract

In the present work we analyze nano-particles of gold and palladium using a combination of High Resolution Electron Microscopy (HREM) and image processing techniques. The experimental results are compared with calculations of images using dynamical diffraction theory. We focus mainly on the decahedral (D_h) and icosahedral (Ic) Particles. We found that the decahedral particles correspond well with the model for a perfect MPT. The icosahedral particle on the other hand appears to be much more distorted than the MPT model predicts. Images of polycrystalline and amorphous particles are also shown. No significant differences between Au and Pd were found.
