Graphene has recently emerged as a serious contender for the post Silicon era. Graphene NanoRibbon (GNR) devices have similar performance characteristics as Carbon Nano Tube (CNT) ones. However, lithographic patterning methods applied to graphene avoids the degree of chirality control and alignment issues typical of CNTs. GNR devices and GNR interconnect can be seamlessly obtained by patterning...

We report a new lithography technique based on electromigration driven material transport for drawing patterns at nanometer scales in ambient conditions. We use a thin metal film as a masking layer and a polymer layer beneath it as a pattern transfer layer. The desired pattern is drawn in the metal layer by etching the metal with a conducting scanning probe assisted by liquid electromigration. ...

Electrohydrodynamic atomisation (EHDA) spraying is a promising materials deposition technique as it allows uniform and regular deposition, and offers a range of other advantages, such as low cost compared with other current techniques, easy set-up, high deposition rate, ambient temperature processing and the capability to generate specific surface topographies. This research is aimed at using E...

Nanopatterning techniques have applications across a wide range of experimental sciences, from controlling cell growth and function [ 1 ] to improving the effi ciency of thin fi lm solar cells. [ 2 ] Approaches developed by the microelectronics industry such as photon-, ionand electron-beam lithography are highly refi ned, producing features with dimensions of just tens of nanometers. Unfortuna...

A patterned gold nanoparticle microarray, functionalized with a nanoscale silicate coating, has been developed for on-chip, high-throughput mass spectrometric analyses of biomolecules with minimal sample preparation and reagent costs. Fabrication was realized by the combination of layer-by-layer functionalization of the nanoparticles with suitable polyelectrolytes, followed by fluidic patternin...
