Field Ion-Scanning Tunneling Microscopy Study of the Ag(110)-O System

Abstract

Atomic-resolution scanning tunneling microscope (STM) images of the Ag(110) clean surface were obtained successfully using a high-performance UHV-mode FI-STM. When the surface was exposured to oxygen, one dimensional linear chains with various separation widths were observed, corresponding to the ( n ×1) LEED patterns. It was concluded that those linear chains consist of Ag O Ag components, similar to the case of the Cu(110)-O system.
