“…These attractive chemical and physical properties make mica a favored material for radio frequency capacitors, high voltage electrical insulators, solid lubrication for nanoscale friction, and atomically flat substrates [8][9][10][11]. The crystal structure imparts mica with perfect basal cleavage [12].…”

We demonstrate an elaborate method to controllably fabricate ultra-thin nanopores by layer-by-layer removal of insulating few-layer mica flakes with atomic force microscopy (AFM). The fabricated nanopores are geometrically asymmetric, like an inverted quadrangular frustum pyramid. The nanopore geometry can be engineered by finely tuning the mechanical load on the AFM tip and the scanning area. Particularly noteworthy is that the nanopores can also be fabricated in suspended few-layer mica membranes on a silicon window, and may find potential use as functional components in nanofluidic devices.

Abstract. We present an overview of template synthesis as it applies to our nanomaterials research. This bottom-up approach is motivated by our desire to find an alternative to the big, top-down approaches to nanoscience, such as clean-rooms and X-ray lithography. Using universally available templates and materials, and very modest synthesis techniques, we have created a variety of interesting and useful structures. Starting with homogeneous ferromagnetic nanowires, we were able to study and manipulate spin-dependent transport. Next, we branched into multi-layer GMR and spin-valve structures for spintronics. As a side trip, we put carbon-encapsulated fullerene nanoparticles into nanopores for ballistic magnetoresistance studies. Carbon nanotube molecules were grown in templates by CVD self assembly. The carbon nanotubes grown using a cobalt catalyzer show spin-valve, ballistic transport, and Coulomb blockade effects. Very recently, we have started to study templated semiconductor nanorods with the amazing result that their behaviour is very similar to that of the carbon nanotubes and can be reduced to a scaling law. Essentially, the template acts as a skeleton for the nanoscale synthesis and macroscale contact of an infinite variety of materials and structures. It is our hope that by the following examples we demonstrate that high quality nanoscience research is available to everybody. PACS

Use of material structure sizes as measuring-normal L. Spieß, Ch. Knedlik Messen von Längen ist ein Vergleichen/Bewerten von erhaltenen Messsignalen mit einem Standard/Kalibriermassstab. Die Nanotechnik erfordert Messgenauigkeiten vom Submeter bis zum Nanometerbereich, d. h. ein Ü berstreichen von 9 Größenordnungen. Messmarken und mögliche Messnormale werden nach ihren Erfordernissen klassifiziert und auf Anforderungen, Genauigkeit, Stabilität, Datenmengen und Machbarkeit analysiert. Für eine Nanopositionier-und -messmaschine werden Vorschläge für eine Realisierbarkeit zusammengefasst.Schlagworte: Kalibriermaßstab, Kristallgitterkonstanten, Röntgenbeugung, Elektronenmikroskopie, Mikrostrukturen Lengths measurement is a comparison/evaluating of received measuring signals with a standard/calibration yardstick. The nano-technology requires measuring accuracies from the submeter to the nanometer range, i.e. a range over 9 orders of magnitude. Strobes and possible measuringnormal are classified according to their requirements and analyzed on requirements, accuracy, stability, data sets and feasibility. For nano-position-and nano-measuring-maschine are summarized suggestions for a feasibility.
