摘要
Initial stages of Si molecular beam epitaxy on vicinal Si (001) substrates were investigated using scanning tunneling microscopy. It was found that at temperatures around 750 K first a preferential growth of one type of terrace occurs, leading to the formation of a single-domain surface. During continued growth both step flow and nucleation of islands occur. Disordered areas can block the step flow and antiphase disorder offers preferential nucleation sites. © 1990, American Vacuum Society. All rights reserved.
