At Ts &ge; 580&deg;C, increasing y and Ts leads to increase in the fraction of dicarbon complexes and the formation of periodic bulk planar structures consisting of ordered Si4C layers which form as a result of C surface segregation. (2) In contrast to Si1-yC y/Si(001), I find that irrespective of y and Ts values, complete substitutional C incorporation in Ge1-yCy/Ge(001) is not possible. A fraction of the total C concentration is always incorporated in nanoclusters. Increasing y and/or Ts leads to an increase in the fraction of C in nanoclusters due to a higher C-C encounter probability at the growth surface. (Abstract shortened by UMI.).
