Abstract
The growth of up to ten-monolayer-thick Fe films on a Au(001) surface was investigated during deposition at room temperature and during annealing, using low-energy electron diffraction and x-ray photoemission spectroscopy, as well as locally with low-energy electron microscopy and photoemission electron microscopy. The growth proceeds with a submonolayer of Au segregating on the surface of Fe, which is in agreement with previous studies. Annealing was found to be critical for the presence of Au on the Fe surface. Our study identifies a spatially inhomogeneous Au segregation mechanism which proceeds by the formation of cracks in the Fe film, starting at the annealing temperature of 190 degrees C, through which Au diffuses towards the surface. As a result, a system with a nonuniform surface electronic structure is obtained. This study shows the necessity to employ spatially resolved techniques to fully understand the growth modes of the layered epitaxial systems.
