Electronic transport in graphene nanoribbon junctions

Graphene nanoribbons (GNRs) - one-dimensional strips of graphene - share many of the exciting properties of graphene, such as ballistic transport over micron dimensions, strength and flexibility, but more importantly, they exhibit a tunable band gap that d ...

Design, Modeling, and Control Methods for Fluid-Mediated Programmable Self-Assembly of Resource-Constrained Robotic Modules

Bahar Haghighat

The newly emerged and quickly growing science of nanotechnology has been recognized as one of ``the twenty-first century's great leaps forward in scientific knowledge''. Self-assembly provides a powerful enabling technique for nanotechnology by providing a ...

Direct-write nanoscale printing of nanogranular tunnelling strain sensors for sub-micrometre cantilevers

Georg Fantner, Jonathan David Adams, Maja Dukic Pjanic

The sensitivity and detection speed of cantilever-based mechanical sensors increases drastically through size reduction. The need for such increased performance for high-speed nanocharacterization and bio-sensing, drives their sub-micrometre miniaturizatio ...

Ultra-rapid prototyping of flexible, multi-layered microfluidic devices via razor writing

Matthias Lütolf, Nathalie Brandenberg, Steffen Cosson

The fabrication of microfluidic devices is often still a time-consuming and costly process. Here we introduce a very simple and cheap microfabrication process based on "razor writing", also termed xurography, for the ultra-rapid prototyping of microfluidic ...

Core-shell InGaN/GaN nanowire light emitting diodes analyzed by electron beam induced current microscopy and cathodoluminescence mapping

Hua Zhang, Gwénolé Jean Jacopin

We report on the electron beam induced current (EBIC) microscopy and cathodoluminescence (CL) characterization correlated with compositional analysis of light emitting diodes based on core/shell InGaN/GaN nanowire arrays. The EBIC mapping of cleaved fully ...

Automated Real-Time Control of Fluidic Self-Assembly of Microparticles

Jürgen Brugger, Alcherio Martinoli, Massimo Mastrangeli, Felix Stephan Schill, Helmut Knapp

Self-assembly is a key coordination mechanism for large multi-unit systems and a powerful bottom-up technology for micro/nanofabrication. Controlled self-assembly and dynamic reconfiguration of large ensembles of microscopic particles can effectively bridg ...

Site-Specific Self-Assembled Liquid-Gated ZnO Nanowire Transistors for Sensing Applications

Klaus Kern, Kannan Balasubramanian, Vivek Pachauri

A scalable bottom-up solution-based approach for the site-specific realization of ZnO nanowire (ZnO-NW)-based field-effect transistors for sensing applications in liquids is reported. The nanowires are grown across pre-defined electrodes patterned by photo ...

Supramolecular control of the magnetic anisotropy in two-dimensional high-spin Fe arrays at a metal interface

Klaus Kern, Harald Brune, Magalí Alejandra Lingenfelder, Pietro Gambardella, Sebastian Stepanow, Sylvain Clair, Alexandre Dmitriev

Magnetic atoms at surfaces are a rich model system for solid-state magnetic bits exhibiting either classical(1,2) or quantum(3,4) behaviour. Individual atoms, however, are difficult to arrange in regular patterns(1-5). Moreover, their magnetic properties a ...

Two-dimensional supramolecular architectures and metallic nanostructures on pre-structured surfaces studied by scanning tunneling microscopy

Régis Decker

In this thesis, we present Scanning Tunneling Microscopy investigations of two-dimensional supramolecular architectures and metallic nanostructures on pre-structured surfaces. We studied different self-assembled supramolecular architectures formed by linea ...
