Two-dimensional phase separation in a Co-Cr random binary alloy on a W(110) surface was confirmed with ultra-high-vacuum scanning tunneling microscopy. With 1.1 ML Co and 0.1 ML Cr co-deposited at room temperature, the film shows a kinetically limited structure. Upon annealing, phase separation between Co and Cr-rich phases of ∼100 Å size was observed. Evidence of compositional inhomogeneity was observed in Cr-rich phases but not in Co-rich phases.
