    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: 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 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.
