20220026464 · 2022-01-27 ·

The surface of the atomic force microscopy (AFM) cantilever is defined by a main cantilever body and an island. The island is partly separated from the main body by a separating space between facing edges of the main body and the island. At least one bridge connects the island to the main body, along a line around which the island is able to rotate through torsion of the at least one bridge. The island has a probe tip located on the island at a position offset from said line and a reflection area. In an AFM a light source directs light to the reflection area and a light spot position detector detects a displacement of a light spot formed from light reflected by the reflection area, for measuring an effect of forces exerted on the probe tip.

Compensating control signal for raster scan of a scanning probe microscope

The invention relates to a measuring device for a scanning probe microscope that includes a sample receptacle which is configured to receive a measurement sample to be examined, a measuring probe which is arranged on a probe holder and has a probe tip with which the measurement sample can be measured. A displacement device is configured to move the measuring probe and the sample receptacle relative to each other, in order to measure the measurement sample, such that the measuring probe, in order to measure the measurement sample, executes a raster movement relative to said measurement sample in at least one spatial direction. Movement measurement signals indicating a first movement component in a first spatial direction that disrupts the raster movement and a second movement component in a second spatial direction that disrupts the raster movement, which second spatial direction extends transversely to the first spatial direction. Compensating control signal components cause a first countermovement which substantially compensates for the first disruptive movement component in the first spatial direction, and/or cause a second countermovement which substantially compensates for the second disruptive movement component in the second spatial direction.

AFM imaging with creep correction

An atomic force microscope (AFM) and method of operating the same includes a separate Z height sensor to measure, simultaneously with AFM system control, probe sample distance, pixel-by-pixel during AFM data acquisition. By mapping the AFM data to low resolution data of the Z height data, a high resolution final data image corrected for creep is generated in real time.
