摘要：
We have investigated Benzotriazole (BTA) adsorption structures and kinetics on the clean Cu(110) and oxygen reconstructed Cu(110)-2 x 1 surfaces. The first atomicaly resolved scanning tunneling microscope (STM) images showed that BTA adsorbed on the clean Cu(110)-1 x 1 surface to form the c(4 x 2) commensurate structure, agreeing the c(4 x 2) LEED pattern. On the other hand, STM images of BTA adsorbed on the oxygen induced Cu(110)-2 x 1 surface were a fully disordered structure. In kinetic point of view, BTA molecules should adsorb preferentially on the oxygen induced Cu(110)-2 x 1 missing row compared to the clean Cu(110) surface.
