The investigation and manipulation of matter on the atomic scale have been revolutionised by scanning tunnelling microscopy and related scanning probe techniques. This book is the first to provide a clear and comprehensive introduction to this subject. Beginning with the theoretical background of scanning tunnelling microscopy, the design and instrumentation of practical STM and associated systems are described in detail, as are the applications of these techniques in fields such as condensed matter physics, chemistry, biology, and nanotechnology. Containing 350 illustrations, and over 1200 references, this unique book represents an ideal introduction to the subject for final-year undergraduates in physics or materials science. It will also be invaluable to graduate students and researchers in any branch of science where scanning probe techniques are used.

In der vorliegenden Arbeit wurde ein elektrochemisches Raster-Sonden-Mikroskop dazu benutzt, gezielt Nanostrukturen herzustellen und zu charakterisieren. Das elektrochemische Umfeld bietet gegenüber den sonst angewandten Techniken den Vorteil, dass die Über- und Untersättigung an den beiden Arbeitselektroden frei eingestellt werden kann. Diese Methode erlaubt es lokal Nanostrukturen definierter Größe herzustellen. Mittels einer selbst aufgebauten UHV-Apparatur konnten Präparationstechniken zur reproduzierbaren Herstellung von geometrisch hoch definierten STM-Spitzen für nahezu jedes Metall entwickelt werden. Derart qualitativ hochwertige STM-Spitzen ermöglichten erstmals einen Strommessbereich von 10-6 bis10-12 Ampere abzudecken. Die entwickelten Instrumente konnten zur Untersuchung der Systeme Co bzw. Ni auf Au(111)-Substraten eingesetzt werden. Das Verfahren zur Erzeugung magnetischer Nanostrukturen wurde optimiert und erste spektroskopische Messungen an der Fest-/ Flüssiggrenzfläche konnten durchgeführt werden.

Magnetic molecules have attracted lots of interest. In this work, an ultra-stable and low noise scanning tunneling microscopy operating at 400 mK using He-3 (930 mK using He-4) has been developed. The magnetic behavior of different magnetic molecules on substrates, especially the exchange interaction between the magnetic ions, the magnetic anisotropy on the surface, the magnetic excitations as well as the Kondo effect, were studied by using STM.

Accurate measurement at the nano-scale - nanometrology - is a critical tool for advanced nanotechnology applications, where exact quantities and engineering precision are beyond the capabilities of traditional measuring techniques and instruments. Scanning Probe Microscopy (SPM) builds up a picture of a specimen by scanning with a physical probe; unrestrained by the wavelength of light or electrons, the resolution obtainable with this technique can resolve atoms. SPM instruments include the Atomic Force Microscope (AFM) and Scanning Tunneling Microscope (STM). Despite tremendous adv

The highlights of this book include an examination of the use of scanning probe microscopy to characterize a variety of polymeric materials, from polymer single crystals and molecular films to composites and biopolymers. The volume provides a synthesis of critical overviews and important new developments, including applications in atomic resolution, chemical force microscopy, and recognition/nanolithography. It includes a review of basic principles and operational modes, terminology, trends, and a discussion of key industrial applications, such as polymer fibers, polymer composites, and filled polymers. It also includes chapters on biopolymers and living cells and on methods for probing micromechanical properties.
