摘要
The submonolayer Al/ Si(111) 7x7 system has been studied by our group using scanning tunneling microscopy and total-energy calculations. We present a review of our recent results on the formation mechanisms and structural properties of the main reconstructions developed on the Si(111) 7x7 surface upon Al adsorption, including alpha-7x7, root 3x root 3, root 7x root 7 and gamma- phase.
