摘要：

Bulk metallic sample surfaces of Pt, Au, and Mo were etched with HF just before immersing in diffusion pump oil and/or were polished with diamond compounds in the diffusion pump oil. The surfaces were directly observed in the oil using a scanning tunneling microscope (STM), and atomically resolved current images were obtained. It is confirmed that the diffusion pump oil is effective to maintain the fresh surface of metals. The surface flatness is most important for obtaining atomic resolution images for the observation of bulk metals in the oil.
