Abstract: A diamond scanning element, especially for an imaging application, includes a support and a pillar extending from the support. The pillar has a longitudinal axis and the pillar includes a tip with a tapered lateral section with a, preferably constantly, increasing curvature. The tip includes a sensor element, which is a defect, and a flat end facet extending toward the axis with a gradient of less than 10%.

Abstract: The invention relates to a method for providing a probe device for scanning probe microscopy, in particular for atomic force microscopy, wherein a scanning probe microscope is used for measuring a sample by means of a tip which is arranged on a cantilever of the probe device and which has a tip geometry. According to the invention, in a step upstream of the manufacturing process producing the tip, the tip geometry is optimized based on a selected tip basic form with regard to defined, required measurement properties, by computer simulating and evaluating the tip geometry, and modifying the tip geometry according to the evaluation with regard to these measurement properties. The invention further relates to a probe device for scanning probe microscopy, in particular for atomic force microscopy, having a cantilever and a tip formed on the cantilever in the nanometer range, with which samples to be measured can be scanned.

Abstract: Methods are described for the economical manufacture of Scanning Probe and Electron Microscope (SPEM) probe tips. In this method, multiple wires are mounted on a stage and ion milled simultaneously while the stage and mounted probes are tilted at a selected angle relative to the ion source and rotated. The resulting probes are also described. The method provides sets of highly uniform probe tips having controllable properties for stable and accurate scanning probe and electron microscope (EM) measurements.

Abstract: A micro probe array device and method of manufacturing are disclosed. In the micro probe array device, a plurality of working electrodes are arranged in an array form, so that an individual electric signal can be applied to an object for each working electrode. In the micro probe array device, the height of the working electrode may be different, the working electrode and the counter electrode may constitute a double electrode, or the substrate may be made of a flexible material.

Abstract: A sharpening method for a probe tip of an Atomic Force Microscope (AFM) includes the steps of dripping a prepared slurry on a glass slide to form a droplet on the glass slide, where particles of the prepared slurry are diamond powder; infiltrating the tip to be sharpened with the prepared slurry; setting operation mode of the AFM to tapping in the fluid and lowering the probe into droplet till the probe cantilever beam is immersed completely in the droplet; setting vibration parameters, scanning parameters, and sharpening time, performing tip sharpening; and evaluating the sharpening results, and finishing sharpening. When the AFM works in a tapping mode in fluid, the tip of the self-excited oscillating probe is sharpened under the grinding effect of the diamond particles. The method is simple and effective, and easy to implement.

Abstract: A method for designing and processing a microcantilever-based probe with an irregular cross section applied in the ultra-low friction coefficient measurement at a nanoscale single-point contact includes: first, establishing a universal theoretical model of the friction coefficient measurement; then, combined with the structural features of the microcantilever-based probe with the irregular cross section, establishing a specific theoretical model of the friction coefficient measurement suitable for the microcantilever-based probe with the irregular cross section; and based on above, combined with constraint conditions such as the friction coefficient resolution, the loadable maximum positive pressure or the measurable minimum friction force, and the atomic force microscope characteristics, etc., designing the microcantilever-based probe with the irregular cross section meeting the measurement requirements.

Abstract: A method of stimulating a MicroElectroMechanical Systems (MEMS) structure (e.g. a cantilever), and an optical sensor for use in such a method, using optical radiation pressure instead of electrostatic pressure, or the like. An optical pulse creates optical radiation pressure which stimulates movement of the MEMS structure and then movement of the MEMS structure may be measures. An interrogating light may be input after the optical pulse to measure movement of the MEMS structure. Advantageously, the same light source can be utilized to stimulate movement of the MEMS structure and to measure movement of the MEMS structure.

Abstract: A scanning probe assembly having a nanometer sensor element defined at a tip apex and its method of fabrication using micro-electromechanical systems (MEMS) processing techniques. The assembly comprises a probe body, a cantilever extending outward, and a hollow tip at the end of the cantilever. A first conductive material is disposed on the hollow tip, followed by a dielectric layer thus embedding the conductive layer. A nanometer hole is milled through the tip, first conductor and dielectric materials. A metal sensor element is deposited by means of electrochemical deposition in the through-hole. A second conductor is deposited on a lower layer. The first and second conductors form electrical connections to the sensor element in the tip. The intra-tip metal, in combination with other layers, may form a thermocouple, thermistor, Schottky diode, ultramicroelectrode, or Hall Effect sensor, and used as a precursor to grow spikes such a nanotubes.
