    Abstract

    Adsorption of Benzo Triazole (BTA) on a Cu(100) surface was studied by angle-resolved ultraviolet photoemission spectrscopy (UPS) and scanning tunneling microscopy (STM). It was found that BTA adsorbed flat up to 1 monolayer, followed by stand-up polymerization above 1 monolayer. LEED (Low Energy Electron Diffraction), XPS (X-ray Photoemission Spectroscopy), UPS, and STM were used to study the surface protection mechanism of BTA on Cu by analyzing the adsorption mechanism. A new model of 3 dimensional polymerization which involves at least 2 BTA-adsorbed layers is suggested.
