Sculpting on polymers using focused ion beam

Controlled formation of nanoscale wrinkling patterns on polymers using focused ion beam

It has previously been shown that focused ion beam irradiation induces a wrinkled skin on the surface of polydimethylsiloxane. Here, it is demonstrated that the wavelength of the induced wrinkles and their morphology can be effectively selected by controlling the acceleration voltage and fluence of the ion beam. The capabilities of the technique are also extended by adopting the maskless patter...

Ion-beam sculpting time scales.

A study of ion sculpting dynamics in SiO2 and SiN using periodically pulsed ion beams reveals material transport that depends strongly on the time structure of the pulsed beams. It is found that significant nanoscale matter transport can occur over second long time scales after the ion beam has been extinguished. A simple phenomenological model described the dynamics of ion beam sculpting in te...

Charging suppression in focused-ion beam fabrication of visible subwavelength dielectric grating reflector using electron conducting polymer

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...

Scanning the Controls: Genomics and Nanotechnology

We outline some of the possible applications of nanotechnology to modern molecular biology and discuss several technologies that can be used to make nanoscale confining environments (channels or post arrays) for long polymers such as DNA. A particular emphasis is placed on making large arrays using nonelectron beam lithography methods. We then discuss how focused ion beam (FIB) milling can be u...
