The probe tip of a scanning probe microscope
WebbA tapping mode scanning probe microscopy (TM SPM) system for surface measurement in nanoscale is developed, of which the main element is a scanning probe consisting of … Webb8.5.3 Scanning probe microscopy. SPM is the name of a group of microscopy techniques in which a physical probe (tip) scans the sample. The interaction between the probe and the sample is measured as a function of their relative position. The scanner is composed by piezoelectric elements working by electronic command.
