Abstract
Ge/Si layers are formed on Si/SiO2/Si(100) substrates and are investigated for different growth temperatures. The Si layer is grown by molecular-beam epitaxy, while the Ge layer is produced by the hot wire chemical vapor deposition. Structural studies are carried out using high-resolution transmission electron microscopy and reflection high-energy electron diffraction. Such structures are promising for the growth of high-quality light-emitting structures on them, which are compatible with silicon radiation-resistant integrated circuits. It is shown that a single-crystal Ge layer can be grown on Si/SiO2/Si(100) via a Si buffer layer by the hot wire chemical vapor deposition, and the difficulties arising during the growth of Ge/Si layers on Si/SiO2/Si(100) are demonstrated.
