Effect of the crystallographic orientation of gold single-crystal electrodes on the occurrence of 2D phase transitions in adsorbed organic monolayers
The influence of the surface structure of a gold electrode on the occurrence of 2D phase transitions in adlayers of uracil and uridine has been studied by cyclic voltammetry. Au(111) surfaces with different step densities have been prepared by cutting the single crystals between 2 and 15.8 degrees of their (111) axis. Results confirm that flat surfaces are a prerequisite for the formation of a 2D condensed physisorbed film.
