Title:
SCANNING PROBE MICROSCOPE
Document Type and Number:
Japanese Patent JP3450460
Kind Code:
B2
Abstract:
PURPOSE: To obtain a scanning probe microscope in which the vibration amplitude of a cantilever is scanned while it is kept constant, by which the uneven image of a sample is detected and which finds the distance dependence of a tunnel current or of evanescent waves without being influenced by the local viscoelastic coefficient of the sample.
CONSTITUTION: By an excitation part, a probe 1 on a cantilever 2 is vibrated in the normal-line direction of a sample 3. The vibration amplitude of the cantilever 2 which is changed by an interaction (an atomic force, an electrostatic force and a magnetic force) acting between the sample 3 and the probe 1 is kept constant. Thereby, while the three-dimensional unevenness of the sample 3 is being detected, the probe 1 traces the surface of the sample 3, and the uneven image of the sample is obtained. At the same time, the distance dependence of a tunnel current or of evanescent waves is found without being influenced by the local viscoelastic coefficient of the sample 3 coming into contact with the tip part of the probe 1.
