Description
High resolution scanning tunneling microscopy has been used to characterize the structural properties and growth mechanism of iron oxide thin film deposited on an Ag(001) substrate. Our experimental results show that the FeO(111) monolayer exhibits a c(2 × 10)/p(2 × 11)/c(2 × 12) unit cell due to lattice matching between the hexagonal overlayer and square substrate lattices. Besides, line defects with locally square atomic coordination are formed due to the excess oxygen in FeO thin film. Our findings provide a platform for understanding the metal oxide-substrate interactions down to atomic scale.
