Abstract

See full text

A novel way for constructing and operating scanning probe microscopes to dynamically measure material properties of samples, mainly their surface hardness, by separating the functions of actuation, indentation and sensing into separate dynamic components. The amplitude and phase shift of higher modes occurring at periodic indentations with the sample are characteristic values for different sample materials. A separate sensor cantilever, connected to the indentation probe tip, has the advantage of a high mechanical amplification of a desired higher mode while suppressing the actuation signal itself. The operational range of the sensor can be extended just by switching the actuation signal to another submultiple of the sensor cantilever's resonance frequency and/or by using more than one sensor cantilever for each indentation tip.
