COVERAGE DEPENDENCE OF SUPERSTRUCTURES AND PHASE-TRANSITIONS OF PB ON THE GE(100)2X1 SURFACE

We report an STM investigation of the Pb adsorption on the Ge(100)2 x 1 surface. With the increase of the Pb coverage, the evolution of the surface structure and surface morphology was revealed on an atomic scale. We also observed some new structures which could not be identified previously in LEED observations. The observed surface morphology evolution indicates that Pb is indeed very reactive and mobile on the Ge(100) surface.Chemistry, PhysicalPhysics, Condensed MatterSCI(E)8LETTER1-3L625-L63131
