Abstract

We study a reversible phase transition of one monolayer of Pb on a Ge(l11) surface over a range of temperature from below to above the transition temperature (∼175°C) with the tunneling microscope. The high temperature l×1 phase is a ordered monolayer l×l 2D solid. Below the transition temperature, Pb atoms are displaced from their ideal T1 positions to form trimers with periodicity.
