First Claim
Patent Images
1. A method for determining properties of a sample surface using an atomic force microscope, comprising:
- applying a first voltage between the sample and a probe;
moving the probe towards the surface of the sample;
stopping movement of the probe towards the surface of the sample when current in the probe is initially detected; and
applying a magnetic field to the probe such that the probe obtains stable contact with the surface of the sample.

Abstract
A method for determining properties of a sample surface using an atomic force microscope includes applying a first voltage between the sample and a probe, moving the probe towards the surface of the sample, and stopping movement of the probe towards the surface of the sample when current in the probe is initially detected. An oscillating magnetic field is applied to the probe such that the probe obtains stable contact with the surface of the sample.
