Abstract

The preparation of gold nanoclusters, dispersed in single-crystal SrTiO 3 (STO) (001) by ion implantation at 300 and 975 K followed by annealing at 1275 K for 10 h, was discussed. High-resolution transmisson electron microscopy (TEM), high-angle annular dark-field imaging in an aberration-corrected dedicated scanning TEM and image simulations were used to study the morphology, size and crystallographic orientation of the Au nanoclusters with respect to the STO matrix. It was shown that gold ion implantation at 300 K leads to amorphization of the STO surface layer, which was corrugated to form bumps and valleys on the surface.
