摘要：
The growth of ordered Mn layers on room temperature and liquid nitrogen cooled Si(111)-1 x 1-Ho surfaces has been studied using scanning tunnelling microscopy. We have shown for 4 ML (monolayers) of Mn grown on a cooled Si(111)-1 x 1-Ho surface that an ordered Mn layer is produced without any, or with only limited, silicide formation. This surface exhibits a (root 3 x root 3)R30 degrees low energy electron diffraction pattern. Significant variations in Mn island sizes have also been seen on the Si(111)-1 x 1-Ho and Si(111)-7 x 7 surfaces for Mn deposited at room temperature and at-180 degrees C.
