Abstract :
Thermally activated processes control nearly all steps in the cleaning, growth and doping of molecular-beam-grown epitaxial films. The temperature dependence of five such processes important in the emerging technology of MBE growth of silicon and germanium films is discussed: (1) SiO2 removal in the initial cleaning of the substrate, (2) surface diffusion during normal MBE growth, (3) the `sticking´ coefficient of dopants evaporated during growth, (4) the process of solid phase epitaxial regrowth and (5) thermal relief of strain in Si-Ge strained superlattices
