Abstract

As a first step towards germanium embedded in silicon wafers, we investigated the surfactant-mediated epitaxy of Ge on structured Si substrates. High-resolution x-ray diffraction (XRD) showed that the Ge-films are <001>-oriented and fully relaxed. Transmission electron microscopy (TEM) inspection in cross-section and plan view revealed uniform films of high structural perfection comparable to those obtained on non-structured wafers. A regular misfit dislocation network is found at the Ge/Si interface at the bottom of the wells, the <111>-oriented side-walls, and the non-etched areas. No defect accumulation was observed at kinks or side-walls. We conclude that the growth mode is not affected by the different surface orientations present on the substrate.
