概要

• 論文の詳細を見る

• A rhenium (Re) tip has been investigated for scanning tunneling microscopy (STM). Most of the Re tips etched electrochemically from poly-crystalline wires were found to have a [112^^-0]-oriented apex by field ion microscopy. A single atom of the tip apex surface has been expected to be stable, because of its high coordination number. The 7×7 reconstructions of silicon (111) surfaces were observed at atomic level by STM using the Re tip. These results suggest that a Re tip with a single apex atom can be one of the most stable tips for STM.
