Scanning tunneling microscopy study of C(2x4)NO/Pt(001)

A structure of NO adsorbed on a Pt(001)-hex R0.7° surface at 300 K was investigated by atomically resolved scanning tunneling microscopy (STM) in an ultra-high vacuum environment. STM images of NO on a Pt(001) surface at 300 K showed a simple c (2×4)-NO superstructure corresponding to a saturation c...

Zusammenfassung:	A structure of NO adsorbed on a Pt(001)-hex R0.7° surface at 300 K was investigated by atomically resolved scanning tunneling microscopy (STM) in an ultra-high vacuum environment. STM images of NO on a Pt(001) surface at 300 K showed a simple c (2×4)-NO superstructure corresponding to a saturation coverage of 0.25. Our STM observation differed from the previous c (2×4) models for the NO adlayer with a saturation coverage of 0.5. At 90 K, extremely small and one-dimensionally grown domains of a quasi- c (2×4) adlayer were observed as clustered islands with a stripe structure of the bare Pt(001)-hex R0.7° surface.
