The Use of Focused Electron and Ion Beams for the Functionalization and Nanostructuring of Polymer Surfaces

Polymers are nowadays actively used in numerous applications owing their low cost and optimized structural properties. Besides, the miniaturization of the novel materials down to nano and even atomic scale needs the use of Electron Microscopy techniques both for imaging and structuring abilities. When used for surface modification, electrons and ions allow altering the surface properties toward...

Nanostructuring lithium niobate substrates by focused ion beam milling

Surface plasmon interference excited by tightly focused laser beams.

We show that interfering surface plasmon polaritons can be excited with a focused laser beam at normal incidence to a plane metal film. No protrusions or holes are needed in this excitation scheme. Depending on the axial position of the focus, the intensity distribution on the metal surface is either dominated by interferences between counterpropagating plasmons or by a two-lobe pattern charact...

Morphology Control of Carbon Nanotubes through Focused Ion Beams

This research demonstrates the capability of controlled, focused ion beam (FIB)–assisted tailoring of morphologies in both multiwall carbon nanotubes (CNTs) and Y junction nonlinear CNT systems through defect engineering. We have shown that a 30 keV FIB Ga ion beam at low ion milling currents of 1 pA can be used to partially reduce the CNT diameter, to provide electrical conduction bottleneck m...
