Dynamical Coulomb Blockade Observed in Nanosized Electrical Contacts

Wolf-Dieter Schneider, François Patthey, I-Po Hong

Electrical contacts between nanoengineered systems are expected to constitute the basic building blocks of future nanoscale electronics. However, the accurate characterization and understanding of electrical contacts at the nanoscale is an experimentally c ...

Flexible polyimide-based force sensor

Martinus Gijs, Jagoda Anna Dobrzynska

We have realized a flexible force sensor, composed of four redundant capacitors, the operation of which is based on the measurement of a load-induced capacitance change. We use polyimide both as flexible substrate and as elastic dielectric between two leve ...

Design, Optimization, and Sensorless Control of a Linear Actuator

Joël Maridor

Electrical contactors are relays for interputing high currents (up to 2000 A). They consist of three main distinct parts: the low voltage circuit, the high voltage circuit and the linear actuator that moves the contact. The purpose of this thesis is to des ...

Device comprising electrical contacts and its production process

Christophe Ballif

The invention relates to a device comprising a conductive surface (12) and electrical contacts (14) by which an electric current is able to be passed. Said electrical contacts (14) comprise conductive seeds (16) deposited on the conductive surface (12), an ...

Current Induced Magnetization Dynamics in Electrodeposited Nanostructures

Elena Murè

In this thesis we make use of the Spin Transfer Torque effect from a continuous microwave current to induce and study the spin dynamics of an individual sub-100 nm nanostructure. The idea that an electrical current can carry a spin angular momentum was int ...

Microwave spin-torque excitation in a template-synthesized nanomagnet

Jean-Philippe Ansermet, Elena Murè

A microwave-compatible lithography-free process is shown to allow the electrical contact of a single nanometric spin valve grown by template synthesis. The complex spin dynamics of a single nanomagnet is revealed by resonant microwave current excitations, ...

Photocurrent and photoconductance properties of a GaAs nanowire

Anna Fontcuberta i Morral

We report on photocurrent and photoconductance processes in a freely suspended p-doped single GaAs nanowire. The nanowires are grown by molecular beam epitaxy, and they are electrically contacted by a focused ion beam deposition technique. The observed pho ...

Spatially Resolved Potential Distribution in Carbon Nanotube Cross-Junction Devices

Klaus Kern, Marko Burghard, Kannan Balasubramanian, Eduardo Jian Hua Lee

Crossed-nanotube junctions, the basic constituents of carbon nanotube networks, are investigated by scanning photocurrent microscopy. The location of the predominant electrostatic potential drop, at the electrical contacts or at the junction, is found to b ...

Scanning photocurrent microscopy of carbon nanostructures

In this thesis, the electronic structures of low-dimensional carbon allotropes have been studied. In particular, the spatially-resolved photocurrent responses of devices comprising carbon nanostructures were investigated through scanning photocurrent micro ...
