    摘要： The present invention provides a technique for eliminating the effect of the thermal drift and other variances and to improve the observing or manipulating accuracy of a scanning probe microscope or atom manipulator by using the technique to correct the aforementioned change in the relative position of the probe and the sample due to heat or other factors during the observation or manipulation. To obtain an image of the sample surface at the atomic level or perform a certain manipulation on an atom on the sample surface, the present invention can be applied to a probe position control method for controlling the relative position of the probe and the sample while measuring an interaction between the objective atom on the sample surface and the tip of the probe. In the present method, the relative position of the probe and the sample are changed while the probe is oscillated relative to the sample in two directions parallel to the sample surface at frequencies of f1 and f2 (S1a). Meanwhile, a point (or characteristic point) where the frequencies f1 and f2 disappear from the measured value of the interaction working in the direction perpendicular to the sample surface is detected (S1b). Then, the relative movement of the probe and the sample is controlled so that the measurement value thereby detected is maintained (i.e. the characteristic point is tracked; S1c), and the speed of the aforementioned relative movement is determined (S1d). Subsequently, the relative position control is corrected using the detected speed (S2).

    摘要： A method for analyzing a sample in a liquid is provided, which is suitable for easily and reliably preventing a liquid for analysis from being evaporated. When the sample in the liquid is observed by using a scanning probe microscope (SPM), a sealing liquid (17) immiscible with a liquid for analysis (16) is filled around the liquid for analysis (16), in which a sample (13) and a probe (15) are immersed, so as to form a sealing state, in which the liquid for analysis (16) is isolated from an external gas. The SPM enables the probe (15) disposed on a front end of a cantilever (14) to approach a surface of the sample (13) immersed in the liquid, scans the surface of the sample, and detects an interaction between the sample (13) and the probe (15), thereby generating an image.

    摘要： A frequency shift Δf obtained by an FM-AFM can be expressed by a simple linear coupling of a ΔfLR derived from a long-range interaction force and a ΔfSR derived from a short-range interaction force. Given this factor, a Δf curve on an atomic defect and a Δf curve on a target atom on the sample surface are each measured for only a relatively short range scale (S1 and S2), and a difference Δf curve of those two curves is obtained (S3). Since the difference Δf curve is derived only from a short-range interaction force, a known conversion operation is applied to this curve obtain an F curve which illustrates the relationship between the force and the distance Z, and then the short-range interaction force on the target atom is obtained from the F curve (S4). Since the range scale in measuring the Δf curve can be narrowed, the measurement time can be shortened, and since the conversion from the Δf curve into F curve is required only once, the computational time can also be shortened. Consequently, in obtaining the short-range interaction force which acts between the atom on the sample surface and the probe, the time required for the Δf curve's measurement and the computational time are shortened, which leads to accuracy improvement and throughput enhancement.
