[1Ba03]Structural identification of the oxide surface of Nb(110) using atomic force microscopy
*Yuuki Yasui1, Katsuyuki Matsunaga2, Yoshiaki Sugimoto1(1. Department of Advanced Materials Science, The University of Tokyo, 2. Department of Materials Physics, Nagoya University)
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.
