Abstract

The development of surface morphology during homoepitaxial growth on one-dimensionally periodic, patterned Si substrates and subsequent annealing has been investigated using transmission electron Microscopy. Si layers grown by MBE are characterized in terms of facets which develop at a trench edge. 1000 Å thick films deposited at ∼ 600°C on Si substrates develop large (311) facets at the bottom and top of the sidewall. After annealing at high temperatures for short times (∼ 1 hour), the amplitude of corrugation decreases but the surface profile is facetted along its length. The “annealed shape” at the trench edge is shown to consist of several surfaces including: (211), (311), (511), and (711). This evidence suggests that (311) facets develop as a result of the growth kinetics.
