Other Members of the SPM Family,erform measurements in an electrolyte, as in the case of electrochemical STM (ECSTM). In scanning noise microscopy (SNM), the noise of the tunneling current is measured at a compensated thermovoltage. In scanning capacitance microscopy (SCM), the capacitance between probing tip and sample is measure

Prospects for SPM,o handle using today’s processing capabilities. These results clearly show new perspectives for microscopy, where large, complex structures are to be investigated on the nanometer scale. Furthermore, new avenues have been opened up in SFM lithography, where patterns on an area of 1 cm. have been wri

Introduction to Scanning Tunneling Microscopy,ic transducers, a sharp, metallic probing tip is brought into close proximity with the sample. The distance between tip and sample is only a few angstrom units, which means that the electron wave functions of tip and sample start to overlap. A bias voltage between tip and sample causes electrons to

Force Microscopy,end of a cantilever which serves as a force sensor. Either the static deflection of the cantilever or the change in its dynamic properties due to tip—sample forces can be exploited. The limit of force detection is far lower than the force between atoms at lattice distances, explaining the widely use

MFM and Related Techniques,ated by a magnetic field. In fact, every scanning force microscope can be used as a magnetic force microscope, if a tip with a magnetic moment is used. Then the SFM becomes sensitive to magnetic fields emanating from the surface of a sample. However, other types of tips that are sensitive to magneti

Other Members of the SPM Family,but some tips are rather different from standard STM tips. Methods such as scanning near-field optical microscopy (SNOM), scanning ion conductance microscopy (SICM) or photoemission microscopy with scanning aperture (PEMSA), are based on tips with apertures, where light, ions or electrons can pass t
