PROBE CHIP, SCAN HEAD, SCANNING PROBE MICROSCOPY DEVICE AND USE OF A PROBE CHIP
The present document relates to a probe chip for use in a scanning probe microscopy device for holding a probe mounted thereon. The probe chip includes a carrier element having a probe bearing side which is configured for bearing the probe to be extending therefrom as an integral or mounted part thereof. The carrier element further comprises a mounting side configured for mounting the probe chip onto a scan head of the scanning probe microscopy device, wherein the mounting side extends in a longitudinal and lateral direction of the carrier element to be substantially flat. The carrier element towards the probe bearing side thereof is truncated in the lateral direction on either side of a longitudinal axis through a center of the carrier element, such as to enable a rotation of the probe chip over a rotation angle around the longitudinal axis in use when the longitudinal axis is inclined at an inclination angle relative to a substrate surface to be scanned and when the probe is in a measurement position relative to the substrate surface.

Photodetector for scanning probe microscope
A detector device is presented for use in a surface probing system. The detector device comprises an integral semiconductor structure configured to define a cantilever and tip probe assembly, comprising at least one tip formed on the cantilever, wherein an apex portion of said at least one tip is configured as an apertured photodetector comprising a layered structure formed with an aperture of subwavelength dimensions and defining at least one depletion region and an electrical circuit, said subwavelength aperture allowing collection of evanescent waves created at a surface region and interaction of collected evanescent waves with the at least one depletion region thereby causing direct conversion of the collected evanescent waves into electric signals being read by the electrical circuit within said tip apex portion, said integral semiconductor structure being thereby capable of concurrently monitoring topographic and optical properties of the surface being scanned by the tip.

SENSOR PROBE ASSEMBLY
A sensor probe assembly includes a probe, and a sensor assembly coupled to the probe. The sensor assembly measures a physical or electrical characteristic of a surface that the probe is near to or in contact with. The sensor assembly is symmetrically disposed around a center axis of the probe.
Method and tip substrate for scanning probe microscopy
The disclosure is related to a method for performing SPM measurements, wherein a sample is attached to a cantilever and scanned across a tip. The tip is one of several tips present on a substrate comprising at least two different types of tips on its surface, thereby enabling performance of multiple SPM measurements requiring a different type of tip, without replacing the cantilever. The at least two different types of tips are different in terms of their material, in terms of their shape or size, and/or in terms of the presence or the type of active or passive components mounted on or incorporated in the substrate, and associated to tips of one or more of the different types. The disclosure is equally related to a substrate comprising a plurality of tips suitable for use in the method of the disclosure.
