Abstract
⺠Transformation from randomly oriented Au nanoparticles to epitaxial Au nanocrystals upon annealing is revealed by in situ RHEED. ⺠Significant Au nanocrystal crystallization occurs at >500 °C annealing temperatures for nanoparticles that are of â¼2 nm in diameter. ⺠The NCs are faceted as evidenced by the shape of RHEED diffraction spots and electron imaging. ⺠High quality RHEED patterns allow the measurement of thermal expansion coefficients and Debye-Temperature of Au nanocrystals.
