MEASUREMENT METHOD OF ATOMIC FORCE MICROSCOPE IN LIQUID USING GENERAL CANTILEVER AND ATOMIC FORCE MICROSCOPE USING THE SAME

摘要

PURPOSE: A liquid image measuring method of an atomic force microscope using a regular scanning probe, and the atomic force microscope are provided to improve the reliability of the measurement by measuring a liquid image after locating the scanning probe closely to the surface of an object sample. CONSTITUTION: A liquid image measuring method of an atomic force microscope using a regular scanning probe comprises the following steps: approaching the scanning probe by locating the scanning probe closely to the surface of an object sample(S11); monitoring the resonance frequency of the scanning probe by applying various wavelengths to the scanning probe(S12); selecting the resonance frequency of the scanning probe corresponding to the resonance frequency appeared when using the scanning probe in air(S13); and measuring a liquid image using the atomic force microscope(S14).
