Thermal diffusion of C(sub 60) molecules and clusters on Au(111)

Article Abstract:

The structure and dynamics of partial monolayers of C(sub 60) on the Au(111) surface were observed by scanning tunneling microscopy (STM) under ambient conditions. The motion of surface-adsorbed C(sub 60) is predominantly the result of thermal diffusion and the extent of pertubation by the STM tip is determined to be minimal, using a quantitative analysis of a time series of STM images.

Stability of aliphatic dithiocarboxyclic acid self-assembled monolayers on gold

Article Abstract:

Series of experiments were conducted to evaluate the stability of adsorption of aliphatic dithiocarboxylic acids (ADTCAs) self-assembled monolayers (SAMS) on gold. These materials found the applications where temporary nanoscale coatings are needed.

Electron transport in self-assembled bipyridinium multilayers

Article Abstract:

The self-assembly of multiple electroactive layers on gold and the electron transport properties of the films are reported. The results demonstrate that a bipyridinium bisthiol forms stable multilayers on the surface of gold electrodes.
