摘要：

Here we describe the Wulff shape of strontium titanate nanocuboids prepared by a hydrothermal method and annealed at high temperature. Transmission electron microscopy was used to measure the faceting ratios d((110)):d((100)) which are compared with surface energy ratios gamma((110)):gamma((100)) from first-principles calculations. Internal voids attributed to the Kirkendall effect were also measured and show agreement with the external faceting. Experiment and theory are shown to agree strongly within statistical and density functional theory error. (C) 2014 Elsevier B.V. All rights reserved.
