A Unified View on Nanoscale Packing, Connectivity, and Conductivity of CNT Networks

The design of functional structures from primary building blocks requires a thorough understanding of how size, shape, and particle-particle interactions steer the assembly process. Specifically, for electrically conductive networks build from carbon nanot ...

Tuning adatom mobility and nanoscale segregation by twin formation and polytypism

Anna Fontcuberta i Morral, Federico Matteini, Gözde Tütüncüoglu, Luca Francaviglia

Nanoscale variations in the composition of an AlxGa1−xAs shell around a GaAs nanowire affect the nanowire functionality and can lead to the formation of localized quantum emitters. These composition fluctuations can be the consequence of variations of crys ...

Aqueous Nanoscale Systems

Sylvie Roke

In the past five years the Laboratory for fundamental BioPhotonics (LBP) has worked on developing new technology that can access the molecular structure and nanoscale properties of buried aqueous interfaces and aqueous solutions. Using these methods a bett ...

Supramolecular Polymers in Aqueous Media

Maartje Martina Cornelia Bastings

This review discusses one-dimensional supramolecular polymers that form in aqueous media. First, naturally occurring supramolecular polymers are described, in particular, amyloid fibrils, actin filaments, and microtubules. Their structural, thermodynamic, ...

Near-Field Integration of a SiN Nanobeam and a SiO2 Microcavity for Heisenberg-Limited Displacement Sensing

Tobias Kippenberg, Dalziel Joseph Wilson, Ryan Daniel Schilling, Vivishek Sudhir, Amir Hossein Ghadimi

Placing a nanomechanical object in the evanescent near field of a high-Q optical microcavity gives access to strong gradient forces and quantum-limited displacement readout, offering an attractive platform for both precision sensing technology and basic qu ...

Super-resolution imaging of multiple cells by optimized flat-field epi-illumination

Suliana Manley, Kyle Michael Douglass, Christian Sieben, Anna Archetti, Ambroise Justin Lambert

Biological processes are inherently multi-scale, and supramolecular complexes at the nanoscale determine changes at the cellular scale and beyond. Single-molecule localizationmicroscopy (SMLM)(1-3) techniques have been established as important tools for st ...

Statistical nanoscale study of localised radiative transitions in GaN/AlGaN quantum wells and AlGaN epitaxial layers

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Etienne François Olivier Giraud

Compositional disorder has important consequences on the optical properties of III-nitride ternary alloys. In AlGaN epilayers and AlGaN-based quantum heterostructures, the potential fluctuations induced by such disorder lead to the localisation of carriers ...

Large area suspended graphene for nano-mechanical devices

Mihai Adrian Ionescu, Clara-Fausta Moldovan

To address the need for large area dry graphene transfer techniques in Nanomechanical applications we use transfer printing to suspend large areas of graphene on pre-patterned substrates with cavities. We find that using this method, clean suspended graphe ...

Bottom-up engineering of InAs at the nanoscale: From V-shaped nanomembranes to nanowires

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Eleonora Russo, Sonia Conesa Boj, Anna Dalmau Mallorquí, Ignasi Canales Mundet

The ability to rationally tune the morphology of nanostructures is a fundamental milestone in nanoscale engineering. In particular, the possibility to switch between different shapes within the same material system represents a further step in the developm ...

Electrochemical nanostructured biosensors: carbon nanotubes versus conductive and semi-conductive nanoparticles

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Gianluca Piccinini

The aim of this work was to demonstrate that various types of nanostructures provide different gains in terms of sensitivity or detection limit albeit providing the same gain in terms of increased area. Commercial screen printed electrodes (SPEs) were func ...
