STABILITY OF TWO–DIMENSIONAL SURFACE NITRIDES ON TRANSITION METAL ALLOY SURFACES
View through CrossRef
The thermal stability of the two-dimensional surface nitrides CrN, MoN and WN has been studied on transition metal alloy surfaces. The surface nitrides are obtained by means of cosegregation of the constituents on Fe–15%Cr–N(100), Fe–3.5%Mo–N(100) and Fe–9%W–N(100) single crystals. The stability of the surface nitrides decreases in the sequence Cr>Mo>W, similar to the well-known three-dimensional bulk nitrides. All compounds exhibit 1×1 LEED structures, indicating epitaxial stabilization on the corresponding substrate surface. In a narrow temperature range T≈550°C the Fe–9%W–N(100) surface shows c (2×2) ordering of the segregated nitrogen atoms.
