“…There are two main types of SPL. One is a destructive method that physically, chemically, or electronically deforms the substrate's surface to make up the pattern by providing the substrate with energy; [37,[146][147][148] the other is a constructive way in which the patterning is performed by directly transferring chemical species to the surface. [149] Because the sharp tips of a scanning probe microscope with a radius smaller than 10 nm can be neatly and controllably manipulated across the substrate, SPL can be utilized to construct nanogap electrodes.…”

Nanogap electrodes (namely, a pair of electrodes with a nanometer gap) are fundamental building blocks for the fabrication of nanometer‐sized devices and circuits. They are also important tools for the examination of material properties at the nanometer scale, even at the molecular scale. In this review, the techniques for the fabrication of nanogap electrodes, the preparation of assembled devices based on the nanogap electrodes, and the potential application of these nanodevices for analysis of material properties are introduced. The history, the research status, and the prospects of nanogap electrodes are also discussed.

“…1). The underlying etching mechanism is not fully understood, but relies most likely on the local breaking of carbon-carbon bonds underneath the STM tip via field-emitted electrons [37,38]. The tip was always moved transversely over the ribbon starting at the trench and ending on the plateau of the mesa structure as shown schematically in Fig.…”

Electron Interference in Ballistic Graphene Nanoconstrictions

We have realized nanometer size constrictions in ballistic graphene nanoribbons grown on sidewalls of SiC mesa structures. The high quality of our devices allows the observation of a number of electronic quantum interference phenomena. The transmissions of Fabry-Perot like resonances were probed by in-situ transport measurements at various temperatures. The energies of the resonances are determined by the size of the constrictions which can be controlled precisely using STM lithography. The temperature and size dependence of the measured conductances are in quantitative agreement with tight-binding calculations. The fact that these interference effects are visible even at room temperature makes the reported devices attractive as building blocks for future carbon based electronics.

“…Recent successful manipulation, in particular cutting of individual CNTs, has been reported [132] and theoretically explained. [133,134] Also, Ag [135] and CdTe nanowires [136] were machined using SPM. Finally, controlled moving, turning, and stretching of nanomaterials is possible by applying SPM (Fig.…”

In this Progress Report, outstanding scientific applications of scanning probe microscopy (SPM) in the field of materials science and the latest technique developments are introduced and discussed. Besides being able to image the organization of matter with sub‐nanometer resolution, SPM, owing to its basic operating principle, provides the power to measure, analyze, and even quantify properties of matter on the nanometer length scale. Moreover, because of its unique potential to manipulate the organization of atoms, molecules, assemblies, or particles and to structure surfaces in a controlled fashion, in the fields of nanoscience and nanotechnology SPM has become one of the most powerful tools for preparation and analysis of nanostructures and their functionality. Because of the tremendous variety of its applications, only selected—but subjectively exceptional—topics are considered in this Progress Report, showing the full potential of SPM.
