Surface bonding and dynamical behavior of the CH(sub 3)SH molecule on Au(111)

Article Abstract:

A study on adsorption site and the dynamics of rotational motion of chemisorbed CH3SH species at low coverages on Au(111) using scanning tunneling microscopy (STM) and density functional theory (DFT) calculations was conducted. It is revealed that the undissociated CH(sub 3)SH molecule binds to an atop Au(111) site on a detect-free Au(111) surface and prefential binding of CH(sub 3)SH to defect sites on the surface were observed during first stage of adsorption at 80 K.

STM investigation of the photoisomerization of an azobis-(benzo-15-crown-5) molecule and its self-assembly on Au(111)

Article Abstract:

The photoisomerization of azobis-(benzo-15-crown-5) on Au(111) was investigated by scanning electron microscopy (STM) and electrochemical methods. After ex-situ UV irradiation, a new adlayer structure with a different molecular arrangement could be seen on Au(111), although the domain size of the ordered packing is small.

Steric effects on the adsorption of alkythiolate self-assembled monolayers on Au (111)

Article Abstract:

The density functional theory is used to examine the steric effects on the adsorption of self-assembled monolayers on the gold surface. According to the results obtained a flat potential energy surface is observed.
