    • A method of determining material properties of a contact formed between a measurement tip (3) of a microscopic probe (2) and a sample surface (7) of a sample material (6). According to the method, a distance modulation (DM) is applied for modulating a distance (d) between a support (4) of the microscopic probe (2) end the sample surface (7) in a direction (z) essentially normal to the sample surface (7) and wherein a normal force signal indicative of a normal force is measured and demodulated. In said method it is proposed that said material properties be determined using measurement data comprised in the demodulated normal force signal and related to a (concave) buckling deformation of the micro­scopic probe (2) relative to and away from the sample surface (7).

    • The invention concerns a method for examining the surface of samples using a scanning microscope (SEM) comprising a flexible beam with longitudinal extension, whereof the longitudinal measuring tip is arranged precisely relative to a sample surface by means of a fixing device, the spatial position of said measuring tip being sensed by a sensing unit. The microscope is further equipped with at least one ultrasound generator which initiates an oscillation at a give excitation frequency between the sample surface and the flexible beam, whereof the measuring tip is in contact with the sample surface, such that the oscillations imparted to the measuring tip are oriented laterally to the sample surface and perpendicularly to the length of the flexible beam. The torsional oscillations of the flexible beam are sensed and analyzed by means of an evaluation unit. The invention is characterized in that the generation of oscillations is such that the oscillations produced by the measuring tip have a higher harmonic vibration relative to the excitation frequency, the oscillation generation is produced at amplitudes which provoke torsional amplitudes in the flexible beam. Those torsional amplitudes have maximum values which form a substantially constant plateau, even when the torsional amplitudes increase, and, in the range of maximum values, said torsional amplitudes have resonance spectra which develop a dispersion capable of being determined by a plateau width. The method for examining a sample surface consists in using the resonance spectra and, preferably, the plateau value, the plateau width and/or the corresponding resonance spectra increase.

    • Methods of sampling specimens for microanalysis, particularly microanalysis by atom probe microscopy, include steps of forming a study specimen in a first study object (as by use of focused ion beam milling); removing the study specimen from the study object; situating the study specimen on a second study object; and microanalyzing the study specimen. Where the first study object is of particular interest for study, the study specimen may be taken from a functional portion of the first study object so that microanalysis will provide information regarding this functional portion. Where the second study object is of particular interest for study, the second study object may be subjected to manufacturing processes (e.g., deposition of layers of materials) after the study specimen is situated thereon so that the study specimen will provide information regarding the results of the manufacturing process. The study specimen may have study regions formed thereon which are particularly suitable for study by atom probes, e.g., regions bearing raised protrusions, at virtually any point during the process, thereby greatly enhancing the speed and efficiency of specimen preparation.

    • The invention relates to a method for the location-resolved, simultaneous detection of adhesion and friction and optionally of other material properties of a sample surface (30) to be examined. To this end a raster probe (1) is used which comprises a raster probe microscope. Said raster probe (1) and/or the sample (25) with the sample surface (30) to be examined are displaced until the raster probe (1), at a position (34) of the sample surface (30) to be examined, interacts in a defined manner with the same. The raster probe (1) and/or the sample (25) are subjected to a vertical oscillation and a measuring signal is recorded which characterizes the deformation of the raster probe (1). In addition, a second measuring signal is recorded which characterizes the deformation of the raster probe (1), whereby the raster probe (1) and/or the sample (25) are subjected to a horizontal and/or vertical oscillation. The desired material properties are now determined from both of these measuring signals using an appropriate evaluation device. The raster probe (1) and/or the sample (25) are displaced once again in order to record the entire surface area to be examined, and are brought into contact with the sample surface (30) in the above-described manner in order to repeat the described measuring procedure at the next position to be examined. The invention also relates to a suitable raster probe microscope for carrying out this method.
