Abstract

Stoichiometric SiGe and Si4Ge epitaxial films and coherent islands are created on Si(100) via thermal dehydrogenation of H 3SiGeH3 and Ge-(SiH3)4, respectively. The control of morphology and composition x of Si 1-xGex nanostructures at the atomic level is achieved for the first time via CVD growth of single-source precursors containing precise atomic arrangements with direct Si-Ge bonds.
