Co/Pt(110) interface: An x-ray-diffraction study

Surface x-ray diffraction has been used to investigate the growth and struc ture of thin cobalt deposits on a Pt(110) substrate. The substrate exhibits the missing-row reconstruction, which has been checked and refined with cr ystallographic measurements. Co grows in the Stranski-Krastanov mode: an in itial two-dimensional growth followed by three-dimensional crystallites. In the early growth stages, cobalt fills the missing-row sites and mixes with Pt. Subsequent growth results in the formation of long triangular prisms w ith the largest side in contact with the substrate. These crystallites have the fee structure and their lateral faces are 111 planes. [S0163-1829(99)0 9603-4].
