Applied Scanning Probe Methods IV

The Nobel Prize of 1986 on Sc- ningTunnelingMicroscopysignaled a new era in imaging. The sc- ning probes emerged as a new - strument for imaging with a p- cision suf?cient to delineate single atoms. At ?rstthere were two the ScanningTunnelingMicroscope,or STM,andtheAtomicForceMic- scope, or AFM. The STM relies on electrons tunneling between tip and sample whereas the AFM depends on the force acting on the tip when itwasplacednearthesample.These were quickly followed by the M- netic Force Microscope, MFM, and the Electrostatic Force Microscope, EFM.TheMFMwillimageasinglemagneticbitwithfeaturesassmallas10nm.

At this point the sluice gates were opened and amultitudeofdifferentinstrumentsappeared. There are signi?cant differences between the Scanning Probe Microscopes or SPM, and others such as the Scanning Electron Microscope or SEM. The probe microscopes do not require preparation of the sample and they operate in ambient atmosphere, whereas, the SEM must operate in a vacuum environment and the sample must be cross-sectioned to expose the proper surface.

Volumes II, III and IV examine the physical and technical foundation for recent progress in applied near-field scanning probe techniques, and build upon the first volume published in early 2004. The field is progressing so fast that there is a need for a second set of volumes to capture the latest developments. It constitutes a timely comprehensive overview of SPM applications, now that industrial applications span topographic and dynamical surface studies of thin-film semiconductors, polymers, paper, ceramics, and magnetic and biological materials. Volume II introduces scanning probe microscopy, including sensor technology, Volume III covers the whole range of characterization possibilities using SPM and Volume IV offers chapters on uses in various industrial applications. The international perspective offered in these three volumes - which belong together - contributes further to the evolution of SPM techniques.
