Abstract

The piezoelectric sensor for scanning probe microscope with a probe in the form of a glass micropipette has been researched. Resonant frequency and Q-quality of the sensor have been measured in air and liquid environments. The spatial resolution has been shown using a test lattice. The conclusion about an opportunity of using of the sensor with a micropipette in the liquid environment with simultaneous activity in semicontact force mode and in a mode of measurement of ionic currents has been made.


Keywords: scanning force microscope, micropipette.
