Abstract:
We examined the tip-sample interaction of a Si(111) surface processed with HF solution. The interaction length of the probe with its hydrophobic surface is approximately 30, and the frequency responses show an interaction force of elastic type. By contrast, the damping curve on a hydrophilic surface, Si with thin oxide, operates on a longer length of 100. Here, the frequency responses indicate an interaction force of the viscous type.
