Synthesis of carbon nanotubes and characterization of nanotubes as atomic force microscopy tips

Yanki Keles

This thesis describes the synthesis of carbon nanotubes (CNTs) by chemical vapor deposition (CVD) and the evaluation of them as tips of atomic force microscope (AFM) probes. Both arc-discharge and CVD grown nanotubes were investigated as AFM tips. Two meth ...

Manipulation of individual carbon nanotubes

Mirko Milas

Carbon nanotubes the long, cylindrical carbon molecules are the most exciting material discovered lately. They offer the possibility for a large number of applications. My task was to explore the way how we can use multi-walled carbon nanotubes (MWNT) in s ...

Realization and characterization of magnetic multilayer for MFM tips

High resolution magnetic force microscopy plays an important role in the development of magnetic data storage media. Particularly the envisioned increase of the storage density to 1TBit per sqinch within the next five years requires an ongoing development ...

Radial elasticity of multiwalled carbon nanotubes

Harald Brune, Stephan Fedrigo, Ismaël Palaci

We report an experimental and a theoretical study of the radial elasticity of multiwalled carbon nanotubes as a function of external radius. We use atomic force microscopy and apply small indentation amplitudes in order to stay in the linear elasticity reg ...

Engineering molecular nanostructures at surfaces

In the framework of this thesis molecular nanostructures have been engineered on surfaces and are characterized using a variety of techniques. Two types of molecules have been used: carbon nanotubes (CNT) and 4-[trans-2-(pyrid-4-yl-vinyl)] benzoic acid (PV ...

Physico-chemical study of the focused electron beam induced deposition process

Tristan Bret

The focused electron beam induced deposition process is a promising technique for nano and micro patterning. Electrons can be focused in sub-angström dimensions, which allows atomic-scale resolution imaging, analysis, and processing techniques. Before the ...

Reinforcement of single-walled carbon nanotube bundles by intertube bridging

Jürgen Brugger, László Forró, Andras Kis, Andrzej Kulik, Willy Benoit

During their production, single-walled carbon nanotubes form bundles. Owing to the weak van der Waals interaction that holds them together in the bundle, the tubes can easily slide on each other, resulting in a shear modulus comparable to that of graphite. ...

Direct observation of toughening mechanisms in carbon nanotube ceramic matrix composites

William Curtin, Ho Ling Li

The excellent mechanical properties of carbon nanotubes (CNTS) are driving research into the creation of new strong, tough nanocomposite systems. Here, the first evidence of toughening mechanisms operating in carbon-nanotube-reinforced ceramic composites i ...

High Precision Robotics System for Scanning Electron Microscopes

Johann Michler, Jean-Marc Breguet

In this paper we present our latest developments in high precision positioning and handling systems operating inside an SEM. The Laboratory in Scanning Electron Microscope concept (LAB-in-SEM) is proposed along with a description of our piezodriven manipul ...

Mechanical properties of mesoscopic objects

Andras Kis

This thesis describes measurements of the mechanical properties on the nanoscale. Three different mesoscopic tubular objects were studied: MoS2 nanotubes, carbon nanotubes and microtubules. The main goal was to investigate the interplay between the fine st ...
