ABSTRACT
Self-assembled alkyl monolayers that are directly tethered to the silicon surface with a Si–C bond suppress mechanical energy dissipation in megahertz-range micromechanical silicon oscillators as compared to the more common silicon oxide coating. Although not as low loss as freshly prepared H-terminated surfaces, Si–C tethered monolayers are more stable with time. Alkyl monolayers derived from chlorosilanes have much poorer mechanical performance. Both types of monolayers suppress adsorption. © 2004 American Institute of Physics.
