We describe SPIW (scanning probe image wizard), a new image processing toolbox for SPM (scanning probe microscope) images. SPIW can be used to automate many aspects of SPM data analysis, even for images with surface contamination and step edges present. Specialised routines are available for images with atomic or molecular resolution to improve image visualisation and generate statistical data ...
In the first part of this thesis we describe the functioning principle of the scanning hall probe microscope (SHPM), and we present a summary of the theoretical and experimental knowledge on the dipolar-coupled Ising ferromagnet LiHoF4. In the second chapter we present the experimental setup that allows us to perform SHPM imaging at ultra low temperatures. The main components; microscope head, ...
The ability to image complex general three-dimensional (3D) structures, including reentrant surfaces and undercut features using scanning probe microscopy, is becoming increasing important in many small length-scale applications. This paper presents a dexel data representation and its algorithm implementation for scanning probe microscope (SPM) image simulation (morphological dilation) and surf...
Since its introduction in 1986 as a tool for imaging and creating three-dimensional micrographs with resolution down to the nanometer and angstrom scales, the scanning probe microscope (SPM) has increasingly been acclaimed as a quantitative probe of surface forces such as adhesion. The SPM is able to study these important parameters using a technique that measures forces on the probe as it appr...
