Abstract
Ge/Si and Si 1− x Ge x nanostructures were grown on Si(100) at 350 °C substrate temperature with a significant growth rate of about 10 Å min −1 using hot-wire decomposition of disilane and germane in an ultrahigh vacuum environment. A quartz crystal microbalance (QCM) was used to monitor growth rates and to study the influence of feed gas pressures. In-situ X-ray photoelectron spectroscopy measurements allowed us to calibrate alloy stoichiometry monitored by QCM. Ex-situ high-resolution transmission electron microscopy observations demonstrated the 2D epitaxial growth of partly relaxed nanolayers. These promising results may be closely related to a surfactant-like role of atomic hydrogen, which appears as a beneficial sub-product of the hot-wire decomposition process of hydride sources. © 1997 Elsevier Science S.A.
