Abstract
Scanning tunneling microscopy (STM) was used to determine the initial stages in the two-dimensional (2D) to three-dimensional (3D) morphological transition for Ge layers grown on Si(001) at 650°C. It was found that the prepyramid islands serve as precursors for the formation of the larger {105}-faceted, 〈100〉 square-based pyramids. These islands exhibited round bases.
