Adlayer structure of TCNQ molecules on Cu(lll): An in situ STM study

导出

摘要 In situ electrochemical scanning tunneling microscopy (STM) was employed to examine tetracyano-quinodimethane (TCNQ) layer adsorbed on Cu(lll) electrode surface in 0.1 mol/L HC1O4 solution. The TCNQ molecules are found to form highly-ordered long range ad-layer with a (4×4) symmetry. Each TCNQ molecule is adsorbed on Cu(111) surface in flat-lying orientation. The molecules are preferentially aligned with their long axes inthe [ 121 ] direction. A structural model is proposed for the adlayer.
