The structure of theCr(001)-p-(1×1)-Nsurface was studied by use of the tensor low energy electron diffraction (LEED) current-voltage(I–V)analysis. From the LEED diffraction pattern observed in the process of cleaning of the Cr(001) surface, N was found to form a(1×1)structure on the Cr(001) surface. ExperimentalI–Vcharacteristic curves for theCr(001)-p-(1×1)-Nstructure were generated by Video LEED System and these experimental results were compared with that obtained through theoretical calculations via the TLEED program to analyze surface structure. As a result, we found that N is adsorbed in the hollow site on the Cr(001) surface. The interlayer distances ofdN1,d12,andd23are found to be 0.251, 1.814, and 1.410 Å, respectively.
