The high superconducting transition temperature of Nb is appreciated for device fabrications while the surface covered with oxide layers prevents preparation of a well-defined interface. Present atomic force microscopy observations clarified the surface atomic arrangement of both Nb and O. A surface model structure is proposed based on density functional theory calculations.
