Abstract
Scanning force microscopy was used to observe the topography of vapor-deposited Au films on various silane monolayers. Thin (1–10 nm) evaporated Au films deposited onto monolayers of (CH3O)3Si(CH2)3X (X = ‒SH, ‒NH2, and ‒CH3) on SiO2/Si(111) display morphologies which are dependent on the nature of the Au-X interaction. Macroscopic adhesion tests indicate that the Au is strongly bound to the amine and thiol surfaces. The electrical resistivity of 8 nm thick Au films deposited on the amine-terminated surface was found to be 7 orders of magnitude lower than that for the thiol-terminated surface, indicating that the amine-terminated surface favors an increased number of nucleation sites. © 1994, American Chemical Society.
