Here we demonstrate, for the first time experimentally, a nanopipette action for metals using multiwalled carbon nanotubes. The process relies on electromigration forces, created at high electron current densities, enabling the transport of material inside the hollow core of carbon nanotubes. In this way nanoparticles of iron were transported to and from electrically conducting substrates.

We present theoretical and experimental results for c field amplified sample stacking (FASS). We use an acid coating to minimize dispersion due to EOF. We mod dimensional electromigration and dispersion of two bac sample ion across an initial concentration gradient. Regu to solve for the concentration fields. Also, we use CCDfluorescence imaging to experimentally measure the u validate the model.

We present a comprehensive physical model for the whole life cycles of electromigration induced voids. Special emphasis is put on explaining the void morphology and its impact on interconnect resistance. Investigations for common twoand three-dimensional interconnect structures are presented. Implications of the theoretical analysis and the simulation results for modern interconnect design are ...

The move towards nanoscale circuits poses new challenges to circuit design. As the dimensions shrink, it is becoming increasingly difficult to control the variance of physical parameters in the manufacturing process, for instance the concentration of dopants, the thickness of the gate and the insulation oxides, the width and thickness of metal wires, etc. This results in decreased yield which i...

The controlled electrochemical synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) as a model conjugated polymer is described here. We show that the morphology of electrochemically synthesized PEDOT can be finely tuned directly in a device, by carefully guiding the nucleation and growth processes as well as electromigration phenomena, resulting in structures with variable electrical properties.

The dynamics of crystal surfaces in the presence of electromigration is analyzed. From a phase field model with a migration force which depends on the local geometry, a step model with additional contributions is derived in the kinetic boundary conditions. These contributions trigger various surface instabilities, such as step meandering, bunching, and pairing on vicinal surfaces. Experiments a...

This review paper gives an overview of capillary electromigration methods used in the analysis of collagen. Analyses of the parent chains as well as of the bromcyane and collagenase fragments of collagens are presented. Methods include capillary zone electrophoresis, capillary gel electrophoresis, micellar electrokinetic chromatography as well as combinations of HPLC and capillary electrophores...
