Abstract
We have investigated the Li-induced phase transition from the Ge(111)3X1:Li to the Ge(111)root 3X root 3:Li reconstruction with photoemission. The Ge( 111)3X1:Li reconstruction can be described as parallel rows of Ge atoms sep arated by single rows of Li atoms. The Ge(111)root 3X root 3:Li reconstruct ion, on the other hands, has to be described in terms of a Li-germanide pha se extending over at least two atomic layers.
