Dynamics of Decanethiol Self-assembled Monolayers on Au(111) Studied by Time-resolved Scanning Tunneling Microscopy
Hairong Wu, Kai Sotthewes, Avijit Kumar, G. Julius Vancso, Peter Schön, and Harold J.W. Zandvliet
paper, the dynamics of four ordered and one disordered phases of
decanethiol on Au(111) are investigated. From STM, I-V and I-t
measurements, the authors conclude that the beta, gamma, chi* and the
disordered phases all exhibit rich dynamics, but in particular, for the
lying-down beta phase, the gold-thiolate complexes on the surface diffuse on the timescale of ~0.1 ms, and in the disordered phase, the alkyl tails flip.
